11. Area of Interest :
Development of new supported catalysts, nano metals and metal oxides for the organic
transformations; Development of new chiral ligands and organocatalysts for
asymmetric reactions; Synthesis of heterocyclic based metallocycles and its catalytic
and biological applications, Eco-economical Processes.
12. International Collaboration :
CNRS-France; RMIT-Australia
13. Recent Significant Achievements:
The main objective is to develop new catalyst materials that perform catalytic
reactions to achieve the highest possible atom economy in an effort to realize cutting
edge technologies and to meet stringent environmental specification in pollution
abatement. Innovative catalysts thus designed for a given reaction offer innumerable
opportunities both in laboratory and industry.
Asymmetric Catalysis
Basic:
The work involves a design and synthesis of new complexes (homogeneous
as well as heterogenisation via immobilisation of the resulting complexes on natural
and synthetic hydrotalcites, nanomaterials for asymmetric hydrosilylation,
epoxidation reactions. The work also involves a design and synthesis of new ligands
from inexpensive amino acid and their metal complex for the asymmetric reactions.
Organometallic Chemsirty
Basic:
Design and development of new hetroatom substituted alkynes for the
preparation of novel annulated heterocyclized metallocycles (Pd, Pt, Ru).
Prepration, characterization and applications in catalysis, material science and
bilological activity.
Highly stabilized Nano metal particles in Catalysis
Basic:
In order to stabilize high surface active nano metal particles, various methods
and stabilizing agents are known to prevent agglomeration during catalytic reaction.
In this direction, we developed highly dispersed and stabilized nano metal/ metal
oxide form inorganic composites, single source precurssor for catalytic organic
transformations. These catalysts have successfully displayed superior activity to the
tune of 5-20 fold excess than the currently known expenssive catalysts including
noble metal based catalysts.
