carbonyl-activated methylene and methyl compounds exhibiting no bromo or diazo substituents could be also transformed into dithioesters by the CAT reaction. The structure of three dithioesters was corroborated by X-ray structural analyses. Supplemental materials are available for this article.

苯、联苯、特别是萘系列的新型芳烃双和三(α-氧代乙烷二硫酸酯)酯是通过相应的重氮乙酰或溴乙酰衍生物与元素硫在三乙胺存在下在干燥条件下反应制备的。 DMF,以及随后产生的二硫代羧酸根阴离子的直接烷基化。添加无水氯化钙(氯化钙活化的硫醇化,或 CAT)可显着促进重氮酮的硫醇化反应。某些没有溴或重氮取代基的羰基活化亚甲基和甲基化合物也可以通过 CAT 反应转化为二硫酯。X 射线结构分析证实了三种二硫酯的结构。补充材料可用于本文。去出版商'
