ZUR REAKTION VON P(III)AMIDEN MIT ORTHOAMEISENSAEUREESTERCHLORIDEN

Both ester diamide, 2a, as well as diester amide, 2b, derivatives of phosphorous acid react with trichlorobenzodioxole, 1, to form the expected ester amide, 3, in small yields only.The main product is the dioxaphosphole, 4.Likewise, trisdimethylaminophosphine reacts with 1 with formation of the dioxaphosphole, 7.This unexpected reaction may be rationalized by assuming competition between N- and P-"diaryloxymethylenation" of the P(III)amide.A similar competition has been observed in the reaction of orthoformate with bis(dimethylamino)chlorophosphine.
