Research Interests

Our group is broadly interested in the chemistry of group 13 and 14 elements. Currently, we are mainly focusing on the synthesis, reactivity, and catalytic applications of germylenes. For the stabilization of germylenes, we use aminotroponiminate, aminotroponate, and dipyrrinate ligand systems. Apart from these, we also have huge interest in bioorganometallic chemistry. For example, (a) the structure of a complex of a germanone isolated by us recently is shown below. Interestingly, we did not use the difficult to make germanone as starting material for the synthesis this compound, but, an easy to make germanium-μ-oxo dimer.

(b) Utilizing the cyanogermylene shown below, we demonstrated the first catalytic application of a well-defined germylene. The catalytic reaction studied was the cyanosilylation of aldehydes.
