An efficient method for the α-chlorination of ketones under basic conditions is described using methyl chlorosulfate. Its applicability for the chlorination of other functional groups has also been studied and it is equally useful for the synthesis of α-chloroesters and amides. Methyl chlorosulfate is described for the first time as a positive chlorine source. Some aldol reactions which occur during the chlorination of some substrates are also reported.

在碱性条件下，使用氯硫酸甲酯对含羰基的化合物进行有效的α-氯化

描述了一种使用碱性氯硫酸甲酯在碱性条件下α-氯化酮的有效方法。还研究了其对其他官能团氯化的适用性，并且对于合成α-氯酸酯和酰胺同样有用。氯硫酸甲酯首次被描述为正氯源。还报道了在某些底物的氯化过程中发生的一些羟醛反应。
