Our research interests span a wide range of inorganic main group and organometallic chemistry. In the more fundamental projects, new reactivity and chemical transformations are targeted with a view to developing new catalysts to either new materials or new processes. In addition, collaborations with industry address the design and development of new catalyst and process technologies for use in commercial applications.

These activities are supported by NSERC and industrial collaborators.

Current fundamental projects are focused in the areas:

• Low valent or low coordinate transition metal complexes and C-H activation
• Reactivity of hemilabile ligand complexes
• Catalytic P-H bond activation: new routes to polyphosphine materials and polymers
• Cyclometallation and hydrophosphination routes to P-based materials and polymers
• P-functionallized polyolefins
• The reactivity of “sterically frustrated” Lewis acid-base pairs

Current industrial/applied research projects are directed towards:

• High temperature olefin polymerization catalysis
• New approaches to o lefin hydrogenation catalysts
• New olefin metathesis catalysts
