Oxidative Functionalization of Metallated β-Diketiminate Analogue

Metal complexes of β-diketiminate analogues have gained profound recent attention by virtue of its multifarious reactivity strategy, functionalization of small molecules, catalytic activity amongst many others.1 In this regard, our recent approach (experimental and theoretical) revealed C-H and C-C bond functionalizations of analogous β-diketiminate as a function of varying metal platform and substrate backbone.2 This includes:

  • Aerobic oxygenation and acylation at central methine carbon of β-diketiminate and β-ketoiminate on selective electron rich {Ru(acac)2} (acac=acetylacetonate) platform.
  • Impact of ancillary ligands (σ-donating acetylacetonate to moderately π-accepting bipyridine to strongly π-accepting phenylazopyridine) as well as ligand backbone on the oxygenation process.
  • Influence of redox non-innocence of β-diketiminate on the rate of oxygenation.
  • Redox-active metal (Ru) versus redox-inactive metal (Zn).

Professor Lahiri's research interests comprise the analysis of new kind of molecules with mixed valency of metal and organic constituents, specifically based on oligonuclear metal complexes with non-innocent: i.e., potentially electron-transferring ligands, including biologically relevant coenzyme models such as quinones, nitrosyl function as well as dye-related nitrogen containing systems. The achievements in ascertaining delicate electronic structures of redox-active molecular frameworks and developing industry-connected transition metal derived catalysts (heterogeneous and homogeneous) for a wide variety of important organic transformations, complement the work.
