硫醇与炔属化合物的加成作用在最近时期受到相当多的注意。文献中的若干报导主要讨论这个反应在合成应用方面的意义,而有关这类加成作用的立体化学和反应机构等问题则研究得很少。为了了解硫醇与炔属化合物加成作用的机构,进而阐明结构与反应性能的关系,作者研究了苯硫酚、对甲苯硫酚及硫醇乙酸与苯乙炔的加成。现将有关立体化学的结果作一简 Addition of mercaptans to acetylenic compounds has received considerable attention in recent times. Several reports in the literature mainly discuss the significance of this reaction in synthesis applications, but few studies on the stereochemistry and reaction mechanism of such additions have been conducted. In order to understand the mechanism of the addition of mercaptan and acetylenic compounds and elucidate the relationship between the structure and the reaction performance, the authors studied the addition of thiophenol, p-toluenethiol and thiol acetic acid to phenylacetylene. Now on the results of stereochemistry for a simple
