The binding of small molecules such as N2, H2, C2H4, etc., to coordinatively unsaturated transition metal centers is an important first step in their activation and conversion to useful chemicals.� Thermodynamic and kinetic parameters governing this process in (PCP)RhI pincer complexes have been examined using a variety of techniques including UV-vis flash photolysis, time resolved infrared (TRIR) spectroscopy and NMR spectroscopy.� Results will be discussed in the context of a proposed mechanism for small molecule coordination to transition metal complexes.
