Selenosulfonation of Conjugated Enynes and the Enyne Equivalent 1,4-Dichloro-2-butyne. Preparation of Sulfonyl-Substituted Allenic Alcohols and Dienes Using Sigmatropic Rearrangements and Organocuprate Additions

Conjugated enynes undergo free-radical selenosulfonation under either photochemical or thermal conditions with Se-phenyl p-tolueneselenosulfonate (1).Addition to the triple bond occurred preferentially with enynes having an acetylenic terminus (6-8) affor

A new preparation of 3-substituted 2-(p-toluenesulfonyl)-1,3-dienes

The title compounds were prepared by addition-elimination reactions of 2-(p-toluenesulfonyl)-2,3-butadien-1-ol. The latter was readily obtained from 1,4-dichloro-2-butyne by selenosulfonation, reductive elimination of chlorine and [2,3] sigmatropic rearra
