Silylene hydrogen chloride

In contrast to the coordination of hydrogen chloride, the complexation energy of the Cs symmetrical silylene-bromoform adduct 19, in which the silylene is coordinated to a bromine center, is calculated to be 97.6 kJ mol1 using the PM3 method.23 However, keeping in mind the inaccuracy of PM3 results concerning the complexation energies of other silylene-... 

The formation of isopropyldichlorosilane can be explained by the reaction of elemental silicon with, hydrogen chloride and isopropyl chloride formed by the hydrochlorination of propylene. As an alternative, it is possible that a silicon-carbon bond is formed by the reaction of a silylene intermediate, generated on the surface of silicon metal powders, with alkene... 

The reaction of 3 with t-butyJ chloride proceeded under clean formation of covalent 6 (Eq. 2). The satisfactory yields and selectivity of these transformations are in marked contrast to the reactions of photochemically generated trimethylsilylphenylsilylene 7 with chloroalkanes, which afforded, depending on the substrate, the silylene insertion product 8 and/or the hydrogen chloride abstraction product 9 in low yield (Eq. 3) [9],...
