The reaction of N3P3(NPPh3)Cl5 with an excess of methoxide yields the 'hydroxy'-derivatives, N3P3(NPPh3)(OMe)4(OH) and N3P3(NPPh3)(OMe)3(OH)2, in addition to the fully methoxylated derivative N3P3(NPPh3)(OMe)5.The analogous reaction of gem-N3P3(NPPh3)(NMe2)Cl4 with methoxide affords N3P3(NPPh3)(NMe2)(OMe)4 and N3P3(NPPh3)(NMe2)(OMe)3(OH).The 'hydroxy'-derivatives exist in their oxophosphaza-tautomeric forms.For the 'monohydroxy'-compounds, the presence of a pair of cis- and trans-oxophosphazadienes is established from 1H and 31P n.m.r. spectroscopic data.

The different mechanistic features involved in the replacement of chlorine and fluorine atoms from N3P3(NPPh3)X5 by methoxide have been identified.An oxophosphazadiene derivative is also isolated.
