Research Project

My research project involves exploring oxide-supported olefin metathesis catalysis derived from perrhenate and methyltrioxorhenium supported on various oxides and preparation of other organorhenium complexes which can then be grafted onto the oxide surfaces to create well-defined active sites.

Synthesis of compounds that can be used as synthons in the generation of larger metal clusters and chains which display interesting solid-state and solution properties that can be of relevance to the chemistry of homogeneous and heterogeneous catalysis is also my current research interest.
