An efficient and highly stereoselective reduction of a gem-dibromocyclopropane to the corresponding monobromocyclopropane under mild reaction conditions was developed using a combination of dimethyl phosphite and potassium carbonate. This reaction provided a simple and practical way for the synthesis of the valuable monobromocyclopropanes and β-monobromoalkenes.

Reaction of α,β-ethylenic and acetylenic phosphonic acid monoesters with (biscollidine)iodine(I) or (biscollidine)bromine(I) hexafluorophosphate led to α,β-unsaturated halides by, without precedent, dephosphorylation reactions.
The regiochemistry and stereochemistry of α,β-epoxysilane ring opening with silyl halides or pseudohalides

The reaction of trimethylsilyl halides with α,β-epoxysilanes leads to either a vinyl halide by addition/elimination or a vinyl enol ether by rearrangement; the route depends upon the nature of the groups attached to the epoxyde ring.With groups β to the silicon that can stabilise an adjacent positive charge the directive effect of silicon towards substitution at the α position is overcome such that the enol ether is obtained.Trimethylsilyl pseudohalides behave similarly except that the intermediate addition product can be isolated.The stereoselectivity of ring opening is found to vary with the reagent. epoxyde / epoxysilane / ring opening / regiochemistry / halosilane
