Abstract

The reaction of HOC6H4CH2CN, N3P3(O2C12H8) 2(OC6H4CH2CN)2 and -[{NP(O2C12H8)}0.8 {NP (OC6H4CH2CN)2} 0.18]n with Cp*Fe(dppe)I in dichloromethane solution and in the presence of T1PF6 affords the new compounds [Cp*Fe(dppe)NCCH2C6H4OH] [PF6] 1 Cp* = C5(CH3)5 [N3P3(O2C12H8) 2(OC6H4CH2CN•Cp*Fe (dppe))2] [PF6]2 2 and the copolymer [{NP{(O2C12H8)}0.8 {NP(OC6H4CH2CN•[Cp*Fe(dppe)] [PF6])2}0.18]n 3 respectively. The ? coordination of the Cp*Fe(dppe) fragment toward the nitrile group is indicated by spectroscopic data. The copolymer 3 is soluble in several organic solvents with no significant cross-linking and has a Mw on the order of 1.260.000. Thermal effects of the incorporation of the organometallic fragment to the copolymer were investigated using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
