Abstract
The formation of 1,2 and 1,4 adducts in the reaction of 5-chloro-2-thiophenethiol, 2-benzofuranthiol, 2-benzothiophenethiol, and 3-methyl-2-benzothiophenethiol with conjugated dienes in the presence of various amounts of ethylsulfuric acid and also without a catalyst was studied. Catalytic acceleration of the reaction with ethylsulfuric acid indicates the heterolytic character of the addition.
