The Cummins group is engaged in the synthesis of reactive metal complexes capable of activating elemental molecules including dinitrogen and tetraphosphorus. The element activation reactions in which we are most interested are those leading to terminal metal-ligand multiple bonds. Atom (e.g. N or P) transfer reactions stemming from the latter metal-ligand multiple bonds are being pursued in order that organonitrogen or organophosphorus compounds may be synthesized from the elements. Following an atom transfer reaction we seek return of the metal complex fragment in a form amenable to recycling and re-use. All of the foregoing goals require the development of new inorganic synthesis methodology and entail the description of definitive new inorganic transformations at an atomic level of mechanistic detail.

Also under investigation in the Cummins group are new molecular constructs with convergent clefts designed to focus oxygenated functional groups onto a central region. This project has the objective of bringing to light new chemical mechanisms for O-O bond formation relevant to the production of solar fuels. This is required in order for the planet’s future energy needs to be satisfied with sunlight. This solar energy project is part of the National Science Foundation Powering the Planet Chemical Bonding Center.
