Abstract

The synthesis of a variety of phosphoryl-substituted sulfines 5 by the reaction of a-silyl carbanions with sulfur dioxide is described. For characterization purposes the prepared sulfines were converted into their cycloadducts 6 with 2, 3-dimethyl-l, 3-butadiene.( Diethoxyphosphory1) phenylsulfine 5a was reacted with alkyllithium to give a-phosphoryl carbanions, which on treatment with aromatic aldehydes gave a,@-unsaturated sulfoxides ...
