Organometallic complexes have enjoyed great success in catalysing and/or mediating organic transformations which otherwise are not possible.The ease of ligand synthesis along with the ability to tailor the functionalities and ligating atoms have led to a plethora of complexes with a wide variety of metals. This has facilitated one, to pick complexes with desired steric and/or electronic parameters to suit their requirement. For efficient catalysis, it would be desirable to have a subtle balance between catalyst stability and reactivity. In the past four decades, it has been more often found, that pincer-metal complexes perform exceedingly well in striking this balance. Not surprisingly, pincer chemistry has grown in leaps and bounds ever-since the first report in 1976 by Moulton and Shaw. In the recent past, pincer-metal complexes have been used in a myriad of applications promoting stoichiometric and catalytic transformations relevant to fuels, commodity chemicals and fine chemicals. The current talk would shed light on the efforts carried out in our lab in utilizing pincer-ruthenium complexes based on bis(imino)pyridine ligands in accomplishing valuable transformations that include but are not limited to N-alkylation, C-alkylation, biofuel and lactic acid production.
