Abstract

1, 4-Dimethyl-2, 3-bis (phenylsulfonyl)-(6a) and 1, 2-bis (phenylsulfonyl)-3, 4, 5, 6- tetramethylbenzene (6b) react with sodium benzenethiolate or 2, 4, 64rimethylbenzenethiolate in MezSO at 120 “C to give mainly products (7a, b, 9, and loa) resulting from the normal substitution of a phenylsulfonyl with an arylthio group together with some (1-11%) 1, 4-dimethyl-(8a) or 1, 2, 3, 4-tetramethyldibenzothiophene 5, 5-dioxide ( ...
