Electroreductive silylation of activated olefins using a reactive metal anode
摘要:
Electroreductive silylation of alpha, beta-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 beta-silyl compounds offering a valuable method for introduction of a silyl group into activated olefins.
Catalyst-Free and Solvent-Controlled Reductive Coupling of Activated Vinyl Triflates with Chlorotrimethylsilane by Magnesium Metal and Its Synthetic Application
Vinylsilanes were directly prepared from the corresponding vinyl triflates under magnesium-promoted reductive conditions in THF with no transition metal catalyst, and gem-bis-silylated compounds were obtained in NMP. Investigation of the redox potential of starting materials and products suggested that reductive coupling reactions of vinyl triflates might be controlled by the reduction potential. A
