Reactions of some nitrosoperfluoroalkanes with trimethylsilyl phosphites

Nitrosotrifluoromethane or nitrosopentafluoroethane reacted with trimethylsilyl diethyl or tris(trimethylsilyl) phosphite to give phosphato-fluorocarbimino- or phosphato-trifluoroacetimino-phosphonates and fluorotrimethylsilane. Some intermediate compounds could be detected by NMR spectroscopy, namely, diethyl (N-trimethylsiloxy-N-trifluoromethyl)- or diethyl (N-trimethylsiloxy-N-pentafluoroethyl)amidophosphate and difluorocarbimino diethyl phosphate. © 1996 John Wiley & Sons, Inc.
