The methoxycyclophosphazenes n (n = 3-6) rearrange on heating to give oxocyclophosphazanes, n.Isomeric products are formed when n = 4-6.The 1H, 31P, and 13C n.m.r. data for the starting materials and the products are presented.The ethoxy- and n-propoxy-derivatives N3P3(OR)6 do not undergo the above rearrangement.The geminal derivatives N3P3R2(OMe)4 (R = Ph or NHBu^t) on heating yield both fully and partially rearranged products, namely dioxaphosphaz-1-enes and oxophosphazadienes, as shown by 270-MHz 1H n.m.r. spectroscopy.The non-geminal derivative N3P3(NMe2)2(OMe)4 gives only the fully rearranged product N3Me3P3(NMe2)2O3(OMe), whose structure has been established from its 1H and 31P n.m.r. spectra.
