报告主题：Transition Metal Catalysed Borylation of C-H and C-X Bonds: Synthesis of Aryl and Alkyl Boronates
报告人：Todd B. Marder教授 （德国维尔茨堡大学）
报告摘要：Aryl- and alkylboronate esters are of great importance in synthesis, as substrates for Suzuki-Miyaura coupling, conjugate additions, and conversion to many functional groups. Newer routes to arylboronates include Pd or Ni-catalyzed cross-coupling reactions of alkoxydiboron or alkoxyborane reagents with aryl halides, and more recently, the selective iridium catalyzed C-H-borylation. The lecture will present some of our work on the Ir-catalyzed borylation of aromatic C-H bonds, applications (e.g., to pyrene chemistry), and our recent development of inexpensive, earth abundant Cu and Zn-catalysts for the borylation of aryl- as well as alkyl halides, and Ni-catalysts for the borylation of aryl fluorides, including novel Rh/Ni dual metal photocatalysis.
