Process for preparing alkylhydrogenchlorosilanes

Alkylhydrogenchlorosilanes of formula I: wherein R are identical or different alkyl radicals, x is 1 or 2 and y is 1 or 2 and the sum of x and y is equal to 3, are prepared by comproportionating alkylchlorosilanes of formula II: wherein R denotes identical or different alkyl radicals, a is 1 or 2 and n is 2 or 3 and the sum of a and n is equal to 4 with hydrogenchlorosilanes of formula III: wherein R denotes identical or different alkyl radicals, b is 0, 1, 2 or 3 and c is 1, 2, 3 or 4 and the sum of b and c is equal to or smaller than 4, in the presence of a catalyst saturated with a hydrogen halide.

Contributions to the chemistry of silicon-sulphur compounds LV. Isosteric isobutyl(isopropoxy)silanethiols. Preparation and spectroscopic properties

The reactions of isobutyl(isopropoxy)silyl bromides i-Bun(i-PrO)3-nSiBr (n=0-3) with H2S in the presence of Et3N yield the corresponding silanethiols, i-Bun(i-PrO)3-nSiSH.The transition energy ?-s* and the IP of Si-S bond, as wel as the first IP of sulphur lone pairs do not change significantly as the number of electronegative i-PrO groups is varied.The geminal anomeric effect seems to be the reason for the increased reactivity of i-Bu(i-PrO)2SiSH and i-Bu(i-PrO)2SiH.
