Synthesis of heterocycles on the basis of arylation products of unsaturated compounds: XX. Reaction of 2-aryl-1,4-benzoquinones with potassium O-butyl carbonodithioate

Abstract

Reactions of 2-aryl-1,4-benzoquinones with potassium O-butyl carbonodithioate gave the corresponding 7-aryl-5-hydroxy-1,3-benzoxathiole-2-thiones. In some cases, 7-aryl-5-hydroxy-1,3-benzoxathiol-2-ones were also formed.* For communication XIX, see [1].
