NEW HETEROFUNCTIONAL CYCLOPHOSPHAZENES WITH CARBONYL AND DOUBLE-BOND FUNCTIONS

Carbonyl- and double-bond-containing cyclophosphazenes, having alpha,b eta-unsaturated ketones residues linked via oxygen bridge to a cycloph osphazene skeleton, have been obtained by reactions of enolate forms o f cyclohexanedione and acetylacetone with hexachlorocyclotriphosphazen e. The respective mono-(I, II) and isomeric disubstituted (non-gem and gem) derivatives were isolated. Structural assignments were based on NMR (H-1 and P-31) and mass spectral data. The method provides a direc t route to hitherto inaccessible unsaturated carbonyl containing cyclo phosphazene derivatives which can serve for various addition reactions .
