설명

일반 설명

This vinylstannane undergoes Stille coupling with a vinyl triflate, giving, after hydrolysis, an α,β−unsaturated ketone, thus acting as an acetyl anion equivalent.

애플리케이션

Electrophilic methyl ketone equivalent used in a recent synthesis of a 13-oxophorbine (chlorophyll) from the corresponding 13-bromochlorin.

Reagent employed in palladium-catalyzed coupling reactions with sulfoxides, α-haloethers, and chlorocyclobutenones. Also used to convert acid chlorides to α-oxygenated enones.
