Thioallyl anions regioselectivity

The regioselectivity of alkylation and carbonyl addition of various thioallyl anions has been examined, particularly with regard to chelation and ion-pairing effects. Thus, Biellmann and co-workers have found that thioallyl-lithium (50), in the presence of [2,2,2]cryptate, adds to acetone exclusively from the... [Pg.93]

The regioselectivity of alkylation has also been studied with cyclic thioallyl anions, with thioallyl-copper systems which involve 5n2 reactions, and with the dianion of prop-2-enethiol (5 ). > The products of addition of aldehyde at the a-position of (50) have been converted into cyclopropane... [Pg.93]
