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).
介绍了一种在 2-羟基硫代苯甲酰胺的氮原子上引入 2-芳酰基苯并呋喃-3-基残基的简单方法。由此得到N-(2-芳酰基苯并呋喃-3-基)-2-羟基硫代苯甲酰胺(4),当它们在乙酸中加热时发生氧-硫位置交换,产生异构体N-(2-硫代芳酰基苯并呋喃-3-基) -2-羟基苯甲酰胺 (6)。
