Perfluorethyllithium + Phosphorus Trichloride,Phosphorus + N-BUTYLLITHIUM + CHLOROPENTAFLUOROETHANE
Avoid temperatures below -90 C
Substitution
Several times in our laboratory, we have experienced a violent decomposition of the ethereal C2F5Cl/n-BuLi solution after the addition of just a few drops of (R)nPCl3=n. In each of these cases, the metal-halogen exchange temperature was maintained below -90 C. We believe that this problem is due to a buildup of starting reagents at low temperatures.
