Me2AlSPh or Me2AlSeMe adds to a,B-unsaturated carbonyl compounds in 1,4-fashion. The resulting aluminium enolates react with aldehydes effectively to afford the adducts of the title anion after formal PhSH(or MeSeH) -elimination.

A reasonably stabilized trichloromethyl anion (TCMA) was formed by the reaction of chloroform with an electrogenerated base prepared by the electroreduction of Zpyrrolidone, and the addition of this TCIvIA to a$unsaturated esters gave the corresponding B-trichloromethyl esters in good yields.
