- Preparation of 2,3-Dihetero-Substituted 1,3-Dienes from Brominated 2-Sulfolenes
-
A general procedure for the preparation of 2,3-dihetero-substituted 1,3-butadienes is described.These dienes are obtained from the thermolysis of the corresponding 3,4-disubstituted 3-sulfolenes, which can be prepared by nucleophilic substitution reaction

- SYNTHESIS AND DIELS-ALDER REACTIONS OF 2,3-BIS(BENZENETHIO)-1,3-BUTADIENE
-
Two different routes to the preparation of 2,3-bis(benzenethio)-1,3-butadiene (1) are reported.Diene 1 is shown to react with maleic anhydride, (E)-1,2-bis(benzenesulfonyl)ethylene and 4-phenyl-1,2,4-triazoline-3,5-dione to give the respective Diels-Alder
