Phenylthiotrimethylsilylmethyllithium(1) was reacted with a variety of electrophiles, including somecontaining two functional groups. α-Phenylthiolketones were obtained from the reaction with esters. The anion(1) underwent either 1,2- or 1,4-addition, depending on the conditions used, with 2-cyclohexen-1-one.
