Structural Spectroscopic and catalytic reactivity studies of coordination complexes containing redox noninnocent Ligands

Synthesis of various redox non-innocent N-donor ligands containing several substitutions on imino and amino nitrogen’s.

Synthesis and isolation of several 3d-5d transition metal complexes and their studies.

A thorough characterization of those newly synthesized complexes by various spectroscopic techniques including CHN analyses, FT-IR, UV-Vis-NIR, NMR, MS and other analytical methods as per requirement. Molecular structure of these complexes will be determined by single crystal X-ray analysis.

Redox properties will be carefully monitored to explore the stability of the complexes in high as well as low valent oxidation states. Their electronic properties will be thoroughly investigated by electronic and EPR spectroscopic techniques. EPR is a very effective tool for chemist to detect the change in spin states of metal as well as of redox non-innocent ligand centers in coordination complexes.

A significant part of the work will be dealt with the reactivity of the compounds towards catalysis. Small molecule activation (e.g.; O2, N2) will be studied; Catalytic activities will be examined in presence dioxygen or oxidants such as H2O2/PhIO. It’s activity will be monitored in epoxidation reactions towards unsaturated alkenes (e.g.; stilbene, styrene etc).

DFT studies will also have to be carried out for understanding reaction pathways.
