4-(ortho-hydroxyphenyl)-1,2,3-thiadiazoles and -1,2,3-selenadiazoles, smoothly transform into 2-benzofuranthiolates and -selenolates. These reactive intermediates can be alkylated in high yield. This reaction sequence could be applied to the synthesis of electron rich thiacrown ethers. The 2-(ortho-aminophenyl)-alkynethiolate analogously forms 2-methylsulfanylindole.

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.
