Graphical Abstract

Abstract

In this investigation, N-substituted phosphinecarboxamides were produced through the reaction of [TBA][P(SiCl3)2] with isonitriles. This method capitalizes on the flexibility of isonitriles as a source of both nitrogen and carbonyl groups, offering a novel route to the generation of PH2-type compounds. This approach is characterized by rapid reaction times, simple procedural requirements, compatibility with a diverse array of substrates, and the conversion of [TBA][P(SiCl3)2] into organic phosphorus compounds. Additionally, we systematically studied the reaction mechanism of isonitrile with [TBA][P(SiCl3)2] through controlled experiments and density functional theory (DFT) calculations.
