Herein it is described that an indium(III) compound effectively catalyzes a reductive insertion into either diaryl or dialkyl disulfides with orthoesters to produce a variety of dithioacetal derivatives. This method could also be adapted to the diselenoacetalization of diselenides. During a series of reductive insertions using this method, it is noteworthy that an orthoester functions as a masked methylene moiety.

一锅法合成二硫缩醛和二硒缩醛：以原酸酯为亚甲基源的铟催化还原插入二硫化物和二硒化物

本文描述了铟（III）化合物与原酸酯有效催化还原插入二芳基或二烷基二硫化物中的还原插入以产生多种二硫缩醛衍生物。该方法也可以适用于二硒化物的二硒缩醛化。在使用该方法的一系列还原插入过程中，值得注意的是，原酸酯起掩蔽的亚甲基部分的作用。
