报告摘要:

CH bond activation has   been established as an increasingly important strategy to access value-added   organics. In contrast to the typical lower-valent metal catalysts, higher   valent Rh(III) catalysts have exhibited exceptionally high activity in   activation of aryl and alkenyl C(sp2)H bond via formation of polarized Rh(III)C bond. Despite   advances, it is desirable to realize efficient CH activation with precise   control of reaction selectivities. This talk will particularly focuses on the   control of reaction enantioselectivity using Rh(III) catalysts stabilized by   chiral Cp ligands. By following desymmetrization of arenes and control of   enantioselectivity in insertion of unsaturated coupling reagents, both axial   and central chirality can be constructed via integration of CH activation,   chemistries of strained ring, and nucleophilic cyclization. In addition, by   following the strategy of substrate activation, enantioselective CC activation of   strained rings has also been realized using Ni(0) catalysts.
