Visible Light-Induced Coordination of Molecular Nitrogen to A Polymer-Bound Cyclopentadienyl-Manganese Complex

Abstract

The visible light-induced reaction of molecular nitrogen with the polymer-metal complex membrane prepared from copolymerization of (vinylmethylcyclopentadienyl)tricarbonylmanganese (VMeCpMn(CO)₃) and styrene has been investigated by means of IR and visible absorption spectra. The results indicated that a mixture of a dinitrogen complex of the manganese moieties, -MeCpMn(CO)₂(N₂), and another unknown chemical species bound to th e polymer were produced. The latter was found to be the same species produced by the visible light irradiation of VMeCpMn-co-styrene under argon atmosphere.
