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 hydrocarbonsolvents. Keywords: Metallacycle: Iridacyle: C-H Bond Activation:

at 59% conversion in 1 h. Abstraction of the CO ligand in these reactions is proposed to involve a metallacyclic intermediate (unobserved) formed by attack of N2O as a 1,3-dipolar reagent on the metal—carbon bond.
