The conversion of alkanes to alkenes is a fundamentally important reaction. Iridium (III) dicarboxylate complexes have been shown to activate C–H bonds and dehydrogenate the alkane to form olefin and iridium (III) hydrides. We previously reported that (dmPhebox)Ir(OAc)2(OH2) will activate n-octane and generate octene in a stoichiometric manner. However, making the reaction catalytic has proven challenging with this system. We have prepared new iridium complexes that are supported by a mono-anionic CCC-pincer ligand. The preparation and reactivity of these new complexes will be discussed. In particular, there will be a focus on their reactivity with aryl and alkyl C–H bonds.
