研究领域

Organic Organic and organometallic synthesis, catalytic oxidations, kinetic studies Topically, my research activities have focused on several aspects of organic chemistry, organometallic chemistry, and physical organic chemistry. Much of my research work is devoted to the development of novel methods for oxidative transformations and for selective catalysis in general. The inspiration comes from biomimetic studies of the predominant oxidation catalysts in Nature, namely the cytochrome P450 enzymes. The ultimate goal is to understand importantly biological oxidation reactions and develop the highly efficient enzyme-like oxidation methods. Our particular interest is to photo-chemically generate highly reactive metal-oxo intermediates that can be utilized for catalytic oxidations. Photochemical reactions are intrinsically advantageous because activation is obtained by the absorption of sunlight, which leaves no residue; whereas most chemical methods involve the use of toxic/polluting reagents. The use of molecular oxygen and solar light in our innovative research is particularly relevant to realizing innovative and economically advantageous processes for conversion of hydrocarbons into oxygenates and, at the same time, to move toward a “sustainable chemistry” that has a minimal environmental impact.
