tetrahedral centre. The respective silane and methane were found to be efficient reducing agents. For model substrates — benzyl bromide and hexadecyl bromide — all four SiH bonds in both branched molecules are equally effective in the UV-initiated reactions. The inefficiency of the ultrasound-promoted reductions is ascribed to low volatility of tetrakis(dimethylsilyl)silane and methane.
