The reactions of ammonia-chloramine mixtures with tetramethyldiphosphine, tetraethyldiphosphine, tetraphenyldiphosphine, and tetraphenylcyclotetraphosphine have been shown to result in the fission of the phosphorus-phosphorus bonds and in the formation of the same products as would be expected from the reaction of ammonia-chloramine mixtures with the corresponding mono- or dihalophosphines. The previously postulated but not isolated compounds [(C6H5)2P(NH2)2]Cl and [(C6H5)P(NH2)3]Cl were obtained. It is postulated that the initial products of the P-P bond fission are R2PCl and R2PNH2. It was also shown that dimethyldiaminophosphonium chloride reacts with PCl5 to yield (CH3)2Cl4P3N3. The mode of formation and the infrared spectrum indicate that this product is a phosphonitrilic cyclic trimer in which both methyl groups are on the same phosphorus atom.
