Synthesis and the Spectral Investigations of Spiro, Ansa and Bridged Derivatives of Cyclochlorotriphosphazenes

Abstract

The reactions of hexachlorocyclotriphosphazatriene, N3P3Cl6 (1) with 2,2-dimethylpropane-1,3-diol yield 9 new cyclophosphazene derivatives. One monospiro, N3P3Cl4[(OCH2)2-CMe2], dispiro, N3P3Cl2[(OCH2)2-CMe2]2 and tris-spiro N3P3[(OCH2)2-CMe2]3 derivatives. An ansa, N3P3Cl4[(OCH2)2-CMe2], and a spiro-ansa, N3P3Cl2[(OCH2)2-CMe2]2 isomers. One dangling, N3P3Cl5[(OCH2)2-CMe2OH], one singly-bridged, N3P3Cl5[(OCH2)2-CMe2] N3P3Cl5, one doubly-bridged, N3P3Cl4[(OCH2)2-CMe2]2N3P3Cl4, and one triple-bridged compounds, N3P3Cl3[(OCH2)2-CMe2]2N3P3Cl3 were also isolated. Product types and relative yields were compared with those arising from propane-1,3-diol. The yields of the spiro, ansa and the bridged products from the reactions of the dimethylpropane-diol system seem to be considerably enhanced relative to those of its unmethylated analogue. The structures of the compounds were determined by using the data obtained from 31P, 1H and 13C N.M.R.
