Organosilicon derivatives of cyclic and high polymeric phosphazenes
Allcock, Harry R.,Brennan, David J.
, p. 231 - 240 (1988)
A new class of compounds is reviewed, the members of which are hybrids of organosilicon and organophosphazene species.They are synthesized either by the reaction of organosilicon halides with organocopper- phosphazene intermediates, or by the interaction of organosilyl or organosiloxy Grignard reagents with chlorophosphazenes.Several of the cyclic trimeric phosphazenes prepared in this way were polymerized by heating to give linear high polymeric phosphazenes with organosilicon side groups.
Reactivity of Hexachlorocyclotriphosphazene towards Alkyl-lithium Reagents

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.
Reactions of Bi(cyclophosphazenes) with Sodium Alkoxides or Aryl Oxides

, p. 2482 - 2490 (2007/10/02)
Bi(cyclophosphazenes) (2) react with nucleophiles such as sodium trifluoroethoxide or sodium phenoxide by two alternative pathways - (a) with cleavage of the P-P ring linkage unit and cleavage of P-Cl bonds to yield organocyclotriphosphazenes (3) or (b) b
