A preparatively facile, highly selective synthesis of bifunctional monosilanes R2SiHCl, RSiHCl2 and RSiH2Cl is reported. By chlorination of R2SiH2 and RSiH3 with concentrated HCl/ether solutions, the stepwise introduction of Si−Cl bonds is readily controlled by temperature and reaction time for a broad range of substrates. In a combined experimental and computational study, we establish a new mode

Tetrasubstitutedsilanes of the general formula R2SiR′2 undergo redistribution reactions quite selectively in the presence of SiHCl3 and chloroplatinic acid. It is the smallest and seemingly the least hindered of the R groups on the tetrasubstitutedsilane which exchange most readily with a chloro group on trichlorosilane.

Organosilicon compounds were directly synthesized from metallic silicon, alkene/alkyne and HCl, EtHSiCl2 being obtained with 47% selectivity from Si, C2H4 and HCl at 513 K, and CH2CHSiHCl2 and EtHSiCl2 with 39 and 23% selectivity, respectively, when C2H2 was used in place of C2H4.
