Palladium(0) catalyzed gem-dimethylation of hexachlorocyclotriphosphazene with tetramethylstannane is described as well as the high yield monoallylation of halogenophosphorus or -boron compounds by allyltrialkylstannanes under photolytic conditions.

Reactions of (NPCl2)3 with LiMe or LiBut and excess of propan-2-ol at -60 deg C in tetrahydrofuran lead to complex reaction mixtures containing cyclic derivatives in 80-90percent yield.The composition of each reaction mixture has been analyzed by 1H and 31P n.m.r. spectrometry.The n.m.r. data thus obtained indicate the presence of a novel cyclophosphazene, viz.NP(H)OPri(NPCl2)2 and several alkyl-substituted cyclophosphazenes.Typical compounds were isolated and characterized as their 2,2,2-trifluoroethoxy-substituted derivatives.The structural characterizations of the reaction products are described together with the appropriate reaction pathways, based on an initial metal-halogen exchange process.

An understanding has been obtained of the complex mechanisms that are followed when alkyl or aryl Grignard reagents react with (NPCl2)3 (2) in tetrahydrofuran.The main products are monoalkylcyclotriphosphazenes (3) and bi(cyclotriphosphazenes) (4).The pre
The reaction of ammonia-chloramine mixtures with phosphorus-phosphorus bonds

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.
