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.
