My research direction driving toward discovery of new reactivity to molecules particularly in organo(metallic) catalysis is largely based on synthetic and mechanistic organometallic chemistry that involves substrate scope study, kinetics, synthesis/isolation/characterization of active or resting catalytic species, and collaborative DFT calculations. The first research program is the development of well-defined and highly modular transition metal catalytic systems for dearomative multiple hydrofunctionalizations of simple, unactivated pyridines to provide unprecedented functionalized N-heterocycles, which can be useful building blocks particularly in drug discovery and development. The specific target catalysis include ligand-controlled regiodivergent double hydroelementation (E = Si, B, Ge, Sn, S, P, etc.), asymmetric double hydroelementation, and asymmetric tandem triple hydrofunctionalizations. The second research program is to accomplish hydroelementation of simple arenes with H[E] reducing agents (E = Si, B, Ge, Sn) via tandem partial hydrogenation-hydroelementation strategy that has been unprecedented. A range of nanoclusters (NC) of (initially) Rh and Ir, and (later) 1st-row transition metals in combination with modular ligands as a stabilizing agent are assumed to hydrogenate simple arenes to partially reduced cyclohexenes. The resultant cyclohexenes are reduced subsequently via facile (asymmetric)hydroelementation reaction (E = Si, B, Ge, Sn) catalyzed by well-defined organo(metallic) species to eventually furnish the functionalized (chiral)cycloalkanes in one-pot.
