Photooxidation of a Tetranuclear Cluster Complex in the Presence of Halocarbons: Photochemistry of the Carbonyl-n5-cyclopentadienyliron (I) Tetramer.

Abstract

Irradiation of carbonyl-n5-cyclopentadienyliron(1) tetramer in the process of halocarbons yields quantitative formation of the cationic tetramer. The quantum yield can be up to 0.21 but depends on wavelength, halocarbon, and co-solvent. The photoactive state is assigned as a charge-transfer-to-solvent (CTTS). A CTTS absorption is observable with a position reciprocal of 30,000 cm which depends on the ease of reduction of the halocarbon. The wavelength dependence of the photochemistry substantiates the assignment.
