Abstract
The complex [(C6H7)Fe(CO)(3)](+) in aqueous solution undergoes a photodecomposition which leads to the formation of cyclohexadiene and Fe2+ with a quantum yield of phi = 0.32 at lambda(irr) = 280 nm. It is suggested that the reactive excited state is of the (Fe-->C6H7) metal-to-ligand charge transfer (MLCT) type. MLCT excitation facilitates an electrophilic addition of a proton at the C6H7 ligand ...
Abstract
The complex [(C6H7)Fe(CO)(3)](+) in aqueous solution undergoes a photodecomposition which leads to the formation of cyclohexadiene and Fe2+ with a quantum yield of phi = 0.32 at lambda(irr) = 280 nm. It is suggested that the reactive excited state is of the (Fe-->C6H7) metal-to-ligand charge transfer (MLCT) type. MLCT excitation facilitates an electrophilic addition of a proton at the C6H7 ligand while in the ground state a nucleophilic attack is favoured. (C) 2003 Elsevier Science B.V. All rights reserved.
