(Z)-AND (E)-1-CHLORO-1,2-BIS(PHENYLSULPHONYL)ETHYLENES: SYNTHONS OF BIS(PHENYLSULPHONYL)ACETYLENE AND OF TERMINAL ACETYLENES IN CYCLOADDITION REACTIONS

The cycloaddition reaction of both isomeric 1-chloro-1,2-bis(phenylsulphonyl)ethylenes 1 leads to the expected Diels-Alder adducts with a number of dienes.The (Z)-isomer is more reactive, but the adducts are dehydrochlorinated with more difficulty and in lower yields than the adducts derived from the cycloaddition of the (E)-isomer.The dehydrochlorinated products are bis(phenylsulphonyl)alkenes which formally derive from the cycloaddition of the hitherto unknown bis(phenylsulphonyl)acetylene.These compounds undergo addition-elimination reaction with Grignard reagents; the products, desulphonylated by sodium amalgam, can be considered as the Diels-Alder adducts of terminal acetylenes.
