We would like to congratulate Dr. Sitaram Acharya for completing his PhD in chemistry from University of Missouri-St. Louis, USA. He has accepted a postdoctoral position at Texas Christian University-Fort Worth, TX, USA. Wishing you all the best Dr. Acharya.
Here is a short description of his research.
Research works are mainly based on synthesis and characterization of water-soluble and air-stable
PTA (PTA = 1,3,5-triaza-7-phosphaadamantane) and DAPTA (N,N’-diacetyl-1,3,5-complexes of
Group 10 metals, platinum and palladium. These novel phosphine complexes were stabilized with a
variety of alkyl, alkynyl, halo, and halo(alkyl) ligands. The catalytic activities of the platinum(II)-
PTA complexes were investigated for the first time in catalytic hydrosilylation reactions of alkenes,
alkynes, and ketones using a variety of hydrosilanes including siloles and silafluorenes. The
complexes were found to be very effective catalysts giving the regioselective products with a very
good turn over number. The catalytic activity of palladium(II)-PTA complexes were investigated in
catalytic Suzuki-Miyaura and copper-free Sonogashira cross-coupling reactions. These complexes
were found to be catalyze these reactions efficiently forming the cross-coupled products with
minimal side reactions.
