Pseudochalcogen Compounds. XVIII. Cyanamidolysis of Organophosphoryl-(phosphonyl-) chloridesCyanamidolytic reactions of organophosphoryl- and -phosphonyl chlorides are leading in dependence on the conditions of the reactions to metal-organo-cyanamidophosphates, M[(RO)2P(Y)NCN], and -cyanamidophosphonates, M[(RO)R'P(Y)NCN], M2[RP(Y)(NCN)2] respectively, as well as to the corresponding organo phosphoryl (phosphonyl) hydrogencyanamides, (RO)2P(Y)NHCN, (RO)R'P(Y)NHCN, RP(Y)(NHCN)2 and to Bis-(organophosphoryl)- and Bis-(organophosphonyl)-carbodiimides, (RO)2P(Y)-NCN-P(Y)(OR)2, (RO)R'P(Y)-NCN-P(Y)R' (OR). (Y: O, S). Conditions for synthesis as well as properties and structures of the new compounds are discussed on the basis of characteristic IR- and 31P-NMR-data.
