A general and convenient double addition of phosphine oxides to isothiocyanates is described. It is a practically useful protocol for the construction of bisphosphinoylaminomethanes. The reaction can be carried out smoothly under metal- and solvent-free conditions. It also features a broad substrate scope, simple operation and purification. A possible mechanism involving a tandem double nucleophilic
描述了将氧化膦一般且方便地双重加到异硫氰酸酯中的方法。这是构建双膦酰基氨基甲烷的实用方法。该反应可以在无金属和无溶剂的条件下平稳地进行。它还具有广泛的底物范围,简单的操作和纯化。提出了可能的机制,包括串联双亲核加成/ H 2 S消除/原位亚胺还原过程。
