The Activation of C-H Bonds with Intermediates Produced by Mild Thermal and Photochemical Decomposition of the Metallacycle (C5Me5)Ir(C(p-CIC6H4)=NOC(=O)(co) in Hydrocarbon Solvents.

Abstract

Thermolysis of the metalacycle at 50 C in benzene or cyclohexane leads initially to the formation of the side-bonded nitrile complex which has been isolated and characterized. Upon further heating at 50 C loss of the nitrile ligand results in C-H bond activation of benzene solvent to generate (N5-C5ME5)IR(H)(C6H5)(CO) in 90% yield. These reactions presumably proceed through the 16-electron metal fragment '(N5-C5ME5)IR(CO)'. Decomposition under mild photolytic conditions in both benzene and cyclohexane also led to C-H activation of the hydrocarbon solvents. Keywords: Metallacycle: Iridacyle: C-H Bond Activation: Nitriles Side-bonded Nitrile complex.
