Thioallyl dianions reaction with aldehydes

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...
