LiAlH4 reduction of SiCl4 releases silane

Explosive,Flammable,Gas Emitter,Pyrophoric

Reduction

We would like to report a potential hazard for the synthetic procedure outlined in Physical Review B (1999, 60, 2704). This contribution is widely referenced and describes a procedure for preparing hydride surface-terminated silicon nanoparticles via lithium aluminum hydride reduction of SiCl4 in micellular tetrahydrofuran (THF) solutions. The authors incorrectly report that this reaction produces hydrogen gas that is presumably released into the "controlled-atmosphere glove box." There is no mention of pyrophoric by-products. We recently attempted to reproduce this reported procedure and performed all our steps on a double-vacuum manifold equipped with argon working gas and an oil bubbler. We used standard experimental techniques for handling air-sensitive compounds. With our experimental design, gas by-products are carried out of the reaction vessel by flowing working gas and are released from the oil bubbler into the ambient atmosphere of the fume hood. From the article cited, there is no reason to expect any adverse events from the procedural difference of interchanging a glove box for a double manifold. The release of hydrogen gas from the oil bubbler into the atmosphere should have been inconsequential. Furthermore, synthetic chemists well-versed in manipulating air-sensitive compounds often find a double manifold more effective than using a glove box. Upon addition of a THF LiAlH4 solution to a THF solution of SiCl4, we observed vigorous bubbling consistent with the literature report. To our surprise, a bright orange flame was released from our oil bubbler. It was impossible for the authors of the aforementioned contribution to make this observation because a gaseous reaction by-product was doubtless captured by the glove box circulation system and was never released into the atmosphere. Fortunately, no one was injured when this "controlled burn" occurred in our laboratory. Subsequent literature searches have revealed that the gas produced is incorrectly identified as hydrogen in the 1999 reference. In fact, the reaction LiAlH4 + SiCl4 t LiCl + AlCl3 + SiH4 occurs in ethereal solutions and has been known for some time to produce pyrophoric silane (J. Am. Chem. Soc. 1947, 69, 1199). While we did isolate some Si nanoparticles from the reaction mixture and confirmed that they were indeed hydride-terminated, we caution other researchers from carrying out this reaction without exercising extreme care.

Lithium aluminum hydride + Friction

Lithium aluminum hydride (LiAlH4) is well-known and widely used as a highly reactive reagent that reduces a wide variety of substances. Given its high reactivity profile, it has also been involved in numerous incidents causing fires small and large. Several research laboratory fires initiated by pulverizing LiAlH4 pellets have brought attention to friction-induced ignition, deficiencies in vendor-supplied Safety Data Sheets, and challenges to researcher training that involve known─but specific─conditions that are incompatible with reactive reagents.

Literature Reference

LITHIUM ALUMINUM HYDRIDE is a powerful reducing agent. React violently on contact with many oxidizing agents. Ignites by friction, especially if powdered. Reacts vigorously with hydroxy compounds such as water, alcohols, carboxylic acids [Mellor 2 Supp. 2:142. 1961]. Caused a violent explosion when used to dry diethylene glycol dimethyl ether: Ignition may have been caused by heat from reaction with impurity water or perhaps decomposition of peroxides in the ether. About 75% of the ether had been removed when the explosion occurred [MCA Case History 1494. 1968]. Reduces carbon dioxide or sodium hydrogen carbonate to methane and ethane at elevated temperatures. These flammable or explosive gases can form when CO2 extinguishers are used to fight hydride fires. Forms explosive complexes with ether, dimethylamine and various tetrazoles. Tetrazoles include, 2-methyl, 2-ethyl, 5-ethyl, 2-methyl-5-vinyl, 5-amino-2-ethyl [US Pat. 3 396 170, 1968].

Reacts violently with air, acids, alcohols, benzoyl peroxide, boron trifluoride etherate, (2-chloromethyl furan + ethyl acetate), diethylene glycol dimethyl ether, diethyl ether, 1,2-dimethoxyethane, dimethyl ether, methyl ethyl ether, (nitriles + water), perfluorosuccinamide, perfluorosuccinamide plus water, tetrahydrofuran, water.

IDENTIFICATION AND USE: Lithium aluminum hydride is a gray-white monoclinic crystalline material which is soluble in ether, tetrahydrofuran, dimethylcellosolve; partially soluble in dibutyl ether and insoluble in dioxane. This chemical is an intermediate in the production of other hydrides. It is used as a reducing agent for over 60 different functional groups, especially for pharmaceutical, perfume, and fine organic chemicals; converts esters, aldehydes and ketones to alcohols and nitriles to amines; source of hydrogen; propellant; catalyst in polymerizations. HUMAN EXPOSURE AND TOXICITY: Causes severe eye and skin burns. It may be harmful if inhaled. This chemical is irritating to skin, eyes, and respiratory system. Symptoms of overexposure include spasms, inflammation and edema of larynx, and bronchi, pulmonary edema, coughing, wheezing, laryngitis, nausea, and vomiting. Solid will burn skin and eyes. The hydrides of aluminum can react with moisture and leave behind hydroxide. The hydrides of lithium in the presence of moisture are readily converted to hydroxides which are highly irritating to the skin by caustic and thermal action. Similar effects can occur on contact with eyes and respiratory mucous membranes. ANIMAL STUDIES: No animal studies could be located.

The main target organs of aluminum are the central nervous system and bone. Aluminum binds with dietary phosphorus and impairs gastrointestinal absorption of phosphorus. The decreased phosphate body burden results in osteomalacia (softening of the bones due to defective bone mineralization) and rickets. Aluminum's neurotoxicity is believed to involve several mechanisms. Changes in cytoskeletal protein functions as a results of altered phosphorylation, proteolysis, transport, and synthesis are believed to be one cause. Aluminum may induce neurobehavioral effects by affecting permeability of the blood-brain barrier, cholinergic activity, signal transduction pathways, lipid peroxidation, and impair neuronal glutamate nitric oxide-cyclic GMP pathway, as well as interfere with metabolism of essential trace elements because of similar coordination chemistries and consequent competitive interactions. It has been suggested that aluminum's interaction with estrogen receptors increases the expression of estrogen-related genes and thereby contributes to the progression of breast cancer (A235), but studies have not been able to establish a clear link between aluminum and increased risk of breast cancer (A15468). Certain aluminum salts induce immune responses by activating inflammasomes. (L739, A235, A236)

Not listed by IARC. IARC classified aluminum production as carcinogenic to humans (Group 1), but did not implicate aluminum itself as a human carcinogen. (L135) A link between use of aluminum-containing antiperspirants and increased risk of breast cancer has been proposed (A235), but studies have not been able to establish a clear link (A15468).

Aluminum targets the nervous system and causes decreased nervous system performance and is associated with altered function of the blood-brain barrier. The accumulation of aluminum in the body may cause bone or brain diseases. High levels of aluminum have been linked to Alzheimer's disease. A small percentage of people are allergic to aluminium and experience contact dermatitis, digestive disorders, vomiting or other symptoms upon contact or ingestion of products containing aluminium. (L739, L740)

Oral (L739) ; inhalation (L739)

Inhalating aluminum dust causes coughing and abnormal chest X-rays. A small percentage of people are allergic to aluminium and experience contact dermatitis, digestive disorders, vomiting or other symptoms upon contact or ingestion of products containing aluminium. (L739, L740)

EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

/HUMAN EXPOSURE STUDIES/ Contamination of aluminum with lithium was suggested as a mechanism for encephalopathy because psychotic patients treated with lithium salts exhibit tremors, early or after several years. Lithium may be a neurotoxin alone, as suggested by the observation that volunteers given lithium carbonate in doses of 1225 +/- 300 mg/day for 7 days when tested in the company of distractors made more errors recalling words than when they received a placebo. Although lithium and aluminum may act similarly, more studies are needed to determine whether lithium contamination contributes to occupational aluminum toxicity. /Lithium contaminated aluminum/

/SIGNS AND SYMPTOMS/ Causes severe eye and skin burns. May be harmful if inhaled. Irritating to skin, eyes, and respiratory system. Symptoms of overexposure include spasms, inflammation and edema of larynx, and bronchi, pulmonary edema, coughing, wheezing, laryngitis, nausea, and vomiting.

/SIGNS AND SYMPTOMS/ From an industrial point of view lithium itself and its salts present no hazard but lithium hydride and its derivatives lithium tetrahydroaluminate and lithium tetrahydroborate are corrosive and irritant.
