New hybrid inorganic-organic polymers containing cyclophosphazenes as pendant groups: Cyclophosphazene ligands containing hydrazone linkages and their conversion to polymers
The reaction of the cyclotriphosphazene N 3 P 3 Cl 5 [O-C 6 H 4 -p-C 6 H 4 -p-CH=CH 2 ] ( 2 ) with 10 equiv of N-methylhydrazine proceeds in a regio-specific manner to afford the multi-functional hydrazide N 3 P 3 [N(Me)NH 2 ] 5 [O- C 6 H 4 -p-C 6 H 4 -p-CH=CH 2 ] ( 3 ). Condensation of 3 with o-hyd...
