Steric and electronic characteristics of the bulky, strongly electron-withdrawing 2,4-(CF3)2C6H3 group are ideally suited to stabilize the unusual form of a diphosphoxane, R2POPR2, the anhydride of a phosphinous acid. The high-yield synthesis and first structural characterization of a tetraorganyl diphosphoxane are described (see structure; C gray, H white, O red, F yellow, P green).
