| Abstract: | Abstract The reactions of hexachlorocyclotriphosphazatriene, N3 P3 CI6, with 2, 2-dimethylpropane-1, 3-diol yield monospiro-, N3 P3 Cl4 (OCH2)2 CMe2, dispiro-, N3 P3 Cl4((OCH2)2CMe2|2, and trispiroderivatives, N3 P3 ((OCH2)2, CMe2]3. An ansa, N3 P3 CI4 (OCH2)2 CMe2]2 and a spiro-ansa, N3 P3 Cl2- ((OCH2), CMe2,]2 and a doubly-bridged compound, (N3 P3 Cl4,)2(OCH2)]2 were also isolated. Product types and relative yields were compared with those arising from propane-1, 3-diol. The yields of ansa products from the reactions of the dimethyl diol seem to be considerably enhanced relative to those of its unmethylated analogue. 31P and 1H n.m.r. spectra are reported. |
