Tetrabutylammonium iodide (TBAI) catalyzes an aerobic oxidative cross-dehydrogenative coupling (CDC) of sulfonyl hydrazides with secondary phosphine oxides in the presence of atmospheric oxygen. This metal-free, efficient and practical approach provides an array of diverse phosphinothioates in very good yields.
