A convenient preparation of mono- or gem-di-halogenoalkanes from α-sulfonyl carbanions and halogenolithiocarbenoids.

Various α-sulfonyl carbanions have been shown to react at low temperature with di- or tri-halogenolithiocarbenoids, to give 1-mono- or 1,1-di-halogenoalkanes.Bromocarbenoids gave better results than their chloro-analogues.Reaction of dibromolithiomethane with α-lithiated sulfones gives a high yield of vinylic bromides, the stereochemistry of which is cleanly E.Evidence is presented that the carbenoid itself is responsible for the reaction, and is not first converted into the corresponding carbene.

ATTEMPTED GENERATION OF HALOCARBENES: PROTODESILYLATION OF DIHALOMETHYLSILANES

Attempts to generate chlorocarbene or bromocarbene from (dichloromethyl)trimethylsilane and (dibromomethyl)trimethylsilane, respectively, under phase transfer conditions results in protodesilylation.The protodesilylation of 1,1-dihalosilanes under phase transfer conditions appears to be general.Phase transfer conditions are also useful for the protodesilylation of other organosilanes.
