Voltammetric study of the photolysis of fac-tricarbonyl-η3-{bis[2-(diphenylphosphino)ethyl]phenylphosphine}molybdenum

Abstract

Voltammetric studies at a channel electrode irradiated with monochromatic visible light have been carried out to demonstrate that the photolysis of fac-Mo(CO)₃{η³-[(Ph₂PCH₂CH₂)₂PPh]} in acetonitrile or dimethylformamide solution leads to the formation of the corresponding mer-isomer. No photofragmentation resulting in the loss of carbon monoxide or phosphine is observed on the voltammetric timescale. Kinetic parameters for the photo-isomerisation are reported.
