摘要

Abstract The title compounds are formed in the reaction of o-phosphinophenole with N- arylimide chlorides of carbonic acids. The primary adducts of formimmonium chlorides, however, undergo [2+ 2]-cycloaddition to furnish 1, 3-diphosphetanes. A further way to 1, 3- benzoxaphospholes consists in the cyclodehydratization of carbonic acid o- phosphinophenyl esters by means of P4O10.
