Main Group and Organometallic Chemistry

The foremost objective of our research is to develop main group catalysts for organic transformations such as C–H, Si–H and H–H bond activation and hydroamination reactions etc. and to develop new efficient synthetic routes to highly functionalized organoborane derivatives via transition metal catalyzed boron-element additions to unsaturated organic compounds. Our group is also interested in synthesis and applications of main group polymers and Al/transition metal based Frustrated Lewis Pairs (FLP’s). Furthermore, we will be exploring the synthesis of multiply bonded main group compounds and its reactivity. The research based on main group chemistry involves extensive chemical synthesis and structural characterization using spectroscopic, crystallographic methods.
