Herein we report the use of commercially available P(i-PrNCH2CH2)3N (1a) as an efficient catalyst for 2-trimethylsilyl-1,3-dithiane (TMS–dithiane) addition to aldehydes at room temperature. The catalyst loading required for these reactions (5 mol %) is the lowest recorded in the literature, and the majority of the reaction times for this transformation are the shortest thus far reported.

在本文中,我们报告了在室温下使用市售P(i -PrNCH 2 CH 2)3 N(1a)作为将2-三甲基甲硅烷基-1,3-二硫杂环丁烷(TMS-dithiane)加成醛的有效催化剂。这些反应所需的催化剂负载量(5mol%)是文献中记录的最低值,迄今为止,该转化的大多数反应时间是最短的。芳基醛底物上具有多种官能团。
