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.
