Following the Hurd-Mori procedure, 4-(2-hydroxyaryl)-1,2,3-thiadiazoles were synthesized from o-hydroxyacetophenones. Treatment of the products with bases gives 2-benzofuranthiolates which can be involved in alkylation and arylation reactions.

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.
