4-(2-Hydroxyaryl)-1,2,3-thiadiazoles as a source of 2-benzofuranthiolates
Petrov,Dehaen,Abramov,Abramova,Androsov
, p. 1510 - 1518 (2007/10/03)
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.
