✦ Synopsis

The title compounds were prepared by addition-elimination reactions of 2-(p-toluenesulfonyl)-2,3-butadien-l-01.

The latter was readily obtained from 1,4-dichloro-2-butyne by selenosulfonation, reductive elimination of chlorine and [2,3] sigmatropic rearrangement of the corresponding selenoxide.
