A Facile Synthesis of Stable Precursors to 2-Alkylated-3-(phenylthio)-1,3-butadienes

3-Sulfolenes 3 which are stable precursors to 2-alkylated-3-(phenylthio)-1,3-butadienes (4) are conveniently prepared. Key Words Sulfur-substituted dienes; 3-Sulfolenes.

4-Bromo-2-sulfolenes. Butadienyl Cation Equivalents

4-Bromo-2-sulfolene and 4-bromo-3-methyl-2-sulfolene react with alkylcuprates to give direct substitution products, with vinyl- or phenylcuprates or sulfur-containing nucleophiles to give allylic substitution products, and with strongly basic nucleophiles to give elimination products.The allylic substitution products and the isomerized direct substitution products are precursors for substituted 1,3-butadienes.Thus, these 4-bromo-2-sulfolenes serve as butadienyl cation equivalents.
