New methods to activate and directly functionalize hydrocarbons to replace energy intensive multi-step methods (e.g. proceeding via syn-gas) are needed. Platinum complexes have been shown to functionalize C-H bonds. However, known catalysts are plagued by undesirable reaction conditions, low conversions and catalyst instability. Promoting heterolytic cleavage of the C-H bond to deliver a carbanion to the metal center and a proton to the ligand backbone may improve catalyst stability by avoiding reactive low valent metal centers in the C-H activation step. Platinum complexes containing pyrazolate based ligands have been investigated for their potential to activate C-H bonds through such metal-ligand cooperative behavior. Neutral and anionic [Pt-Me] complexes have been protonated at the ligand backbone to generate the respective cationic and neutral [Pt-Me] species. The reactivity of these protonated [Pt-Me] complexes has been explored and the results will be presented.<br/>
