Abstract
A simple method for the introduction of a 2-aroylbenzofuran-3-yl residue at the nitrogen atom of 2-hydroxythiobenzamide is described. Thereby N-(2-aroylbenzofuran-3-yl)-2-hydroxythiobenzamides (4) were obtained which undergo an oxygen-sulfur position exchange when they were heated in acetic acid yielding the isomeric N-(2-thioaroylbenzofuran-3-yl)-2-hydroxybenzamides (6).
