REACTIONS OF HETEROAROMATIC THIOLS WITH 1,3-BUTADIENE AND CYCLOPENTADIENE

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.

Synthesis of benzo[b]furan-2-thioles from 4-(2-Hydroxyaryl)-1,2,3- thiadiazoles

4-(2-Hydroxyaryl)-1,2,3-thiadiazoles treated with bases decompose with nitrogen liberation and the formation of benzo[b]furan-2-thiolates. On acidifying the thiolates benzo[b]furan-2-thiols were obtained. 4-(4-and -5-Benzyloxy-2-hydroxyphenyl)-1,2,3-thiadiazoles formed analogously the corresponding benzo[b]furan-2-thiolates whose acidifying afforded polymeric compounds.
