Abstract

Reactions of 2-aryl-1,4-benzoquinones with disodium (2,2-dicyano-1,1-ethylene)dithiolate gave rise either to 1,3-benzodithiol or 1,3-benzoxathiol depending on the character of the aryl substituent. 2-Aryl-1,4-benzoquinones reacted with 3-methylsulfanyl-3-sulfanyl-2-cyanoacrylamide with a higher selectivity: 2-(7-Aryl-5-hydroxy-1,3-benzoxathiol-2-ylidene)-2-cyanoacetamides were obtained in a high yield.
