Mg-promoted regioselective carbon-silylation of α-phosphorylacrylate derivatives
Treatment of aromatic α-phosphorylacrylate derivatives 1a-h with Mg turnings in the presence of trimethylsilyl chloride brought about facile and regioselective C-silylation to give the corresponding β-silylated phosphonates 2a-h in excellent yields. The r
Electroreductive silylation of activated olefins using a reactive metal anode
Electroreductive silylation of α, β-unsaturated esters, nitriles and ketones in the presence of Me3SiCl using a reactive metal anode (Mg, Zn, Al) in an undivided cell afforded the corresponding β-silyl compounds offering a valuable method for introduction of a silyl group into activated olefins.
