Abstract
Alkyliron(III) porphyrins, n-butyliron(III) tetraphenylporphyrin, (TPP)Fe-Bu and n-butyliron(III) tetrakis(pentafluorophenyl)porphyrin, (F20TPP)Fe-Bu have been evaluated as suitable for olefin free-radical polymerization. Butyl radicals dissociated from n-butyliron(III) porphyrin initiated the polymerization reaction, but the ratio of the propagation was low. The GCMS analysis of the reaction mixture of n-butyliron(III) porphyrin and styrene has revealed several products containing two butyl groups, while traces of beta-hydrogen-abstracted products were observed. The crystal structure of (TPP)Fe-Bu has been determined. The structure of the n-butyliron(III) porphyrin reveals the compound containing five-coordinated iron with the average Fe-N distance of 1.973(1) Angstrom and Fe-C of 2.030(2) A. The iron atom is displaced by 0.137 Angstrom from a four nitrogen mean plane. Crystal system is triclinic, and space group is P-1.
