Tetrabutylammonium Iodide

An alternative metal-free, efficient and practical approach for the preparation of phosphinothioates is established via the aerobic oxidative cross-dehydrogenative coupling (CDC) of sulfonyl hydrazides with secondary phosphine oxides catalyzed by tetrabutylammonium iodide (TBAI) in the presence of atmospheric oxygen. The strategy provides an array of diverse phosphinothioates in good to excellent yields. Furthermore, two representative bioactive molecules are synthesized on up to gram scale by utilizing this method.

A highly efficient electrophilic addition of 3-diazooxindoles to H-phosphine oxides under metal-free and base-free conditions is established, leading to phosphinic hydrazides. This method has good chemoselectivity and broad substrate diversity, and provides a facile and green approach for N–P bond formation. The stereoselective synthesis represents a unique example of asymmetric electrophilic addition of diazo compounds as N-terminal electrophiles with phosphorus compounds, affording P-stereogenic phosphinic hydrazides with excellent stereoselectivity.
