HCID 11112867Di(pentafluorophenyl)dichlorosilane

Procedure

180.93 g (0.400 mol) di(pentafluorophenyl)diethoxysilane, 146 mL (2.00 mol, 237.9 g) thionylchloride and 4.92 g (0.0426 mol) pyridinium hydrochloride are refluxed and stirred for 16 h. Excess of SOCl2 is evaporated and di(pentafluorophenyl)dichlorosilane isolated by vacuum-distillation.
