Laboratory of Kinetics of Catalytic Processes
The study of the fundamental features of the mechanisms of cross-coupling reactions to search for new effective "ligand-free" catalysts
A method for distinguishing homogeneous and heterogeneous mechanisms of catalytic reactions complicated by the course of interconversion of several potentially active forms of the catalyst, based on the analysis of the phase trajectories of reactions with similar substrates competing for the same catalyst. The application of this method coupled with the operando spectroscopy technique allowed us to obtain conclusive evidence of a significant contribution of the heterogeneous catalysis in the Suzuki reaction with aryl bromides and significant contribution of
the homogeneous mechanism in the Suzuki reaction with aryl iodides. From the kinetic studies we established the dualistic role of a base in the Suzuki reaction, on the one hand, forming intermediates of the catalytic cycle capable to transmetalation; and, on the other hand, participating in an undesirable formation of borate anions that causes complex dependence of the course and release of the product on the concentration of base. An efficient catalyst system for the production of biaryls from low reactive aryl bromides and aryl boronic acids under mild conditions using simple palladium salts without any ligand.
