"Bifunctionality in Organometallic Catalysis"

Abstract

Synergic participation of two or more chemical functionalities in a catalyst is known to facilitate a difficult chemical process. Both metal-metal and metal-ligand cooperation (MLC) strategies have been implemented in organometallic catalysts. Cooperative participation of two metals in close proximity activates small molecules, controls stereo-electronic factors and promotes product elimination. We earlier developed several bimetallic constructs (M-M) and explored their catalytic utility for a wide range of organic transformation reactions. In a new approach, synthetic catalysts are designed where a cooperating ligand in the vicinity of metal site actively participates in bond–activation process and undergoes reversible chemical transformation to make the catalytic process efficient and selective. Carefully designed ligand scaffolds, which hold the metal ion and simultaneously offer a proton-acceptor unit, have been devised for water activation, hydrogenation and dehydrogenation reactions. This talk would focus on the scope of bifunctionality in organometallic catalysis with relevant examples.
