The 2,4,5-trioxo-1,3-diaza-2-phospholidene trisubstituted, 3, are synthetized in the absence of any base, by the reaction of oxalyle chloride on the primary phosphordiamides 1.The 3 cycles are opened with a Formel bond cleavage in the presence of alcohols and a Formel one in the presence of amines.It can be assumed from the results that Formel pentacoordinate X complex is formed, whose breakdown in the case of amines is slower than the attack on one or the other of the carbonyles.
