REACTIONS OF FERROCENYL AMINES AND ALCOHOLS WITH HEXACHLOROCYCLOTRIPHOSPHAZENE

The reactions of ferrocenyl methanol, ferrocenyl 2-propanol and N-meth yl-2-ferrocenylmethylamine with chlorocyclophosphazenes have been exam ined. The pentachlorocyclotriphosphazene derivative of ferrocenylmetha nol undergoes rapid decomposition via a phosphazene-phosphazane rearra ngement, however when the alcohol function is beta to the cyclopentadi enyl ring modest yields of N3P3Cl5OCHMeCH2C5H4FeCp may be obtained. By way of contrast N-methyl-2-ferrocenylmethylamine gives a broad range of stable derivatives, N3P3Cl6-n[NMeCH2C5H4FeCp](n) (n = 1-3). The sub stitution process follows a predominantly trans non-geminal pathway. T he corresponding reaction with the butylmethacrylate derivative, N3P3C l5O(CH2)(4)OC(O)CMe=CH2 leads to the unexpected geminal product, 2,2'- N3P3Cl4[O(CH2)(4)OC(O)CMe=CH2]NMeCH2C5H4FeCp. Polymers containing the 2-ferrocenylmethylamine function have been obtained by reactions of po ly(dichlorophosphazene) with the ferrocenylamine and by radical additi on polymerization of the aforementioned mixed ferrocenylamino butylmet hacrylphosphazene. The new materials have been characterized by standa rd methologies including P-31 NMR spectroscopy, cyclic voltametry and gel permeation chromatography.
