ofC-chlorovinylmethylchlorosilanes with various alcohols and acetone oxime were investigated. A series of newC-chlorovinylmethylalkoxy- and -isopropylideneiminoxysilanes was characterized by IR and1HNMRspectra. The effect of the number of chlorine atoms inC-chlorovinylmethylchlorosilanes on their reactivity in these reactions was determined.

intermediacy of the alkylidenecarbene CH2:C:. Pyrolysis of (2-chloro-1-fluoroethyl)trifluorosilane gives vinyl chloride via a carbene intermediate, but the trichlorosilyl analogue yields the rearrangement compound dichloro(1,2-dichloroethyl)fluorosilane. 1,2-Difluoroethyl-trifluorosilane and -trichlorosilane both decompose via a non-carbene mechanism involving β elimination.
