Reaction de transfer d'electron phoinduit avec des complexes cluster Fe 4S 4

Abstract

In this paper we describe the photoinduced electron transfer reaction of [N(n-C 3H 7) 4 +] 2[Fe 4S 4(SR) 4] 2- (R  n-C 3H 7 or C 6H 4NO 2), and its dependance on the pH and the wavelength of the light used, and also with addtion of cysteinemolybdenum complex as cocatalyst. The transfer was performed on methylviolegen, acenaphthenequinone and tetracyanoethylene. We report also the possible reversible intramolecular electron transfer of the cluster core to the ligand SC 6H 4NO 2.
