Ni Catalyzed Borylation and Cross-Coupling of Aryl Halides
Rosen et al. devised a new way to synthesize aryl neopentylglycolborane using [(diphenylphosphino)propane]dichloronickel as a catalyst. The resulting aryl is then cross-coupled with a variety of aryl halides using [(diphenylphosphino)etane]dichloronickel as a catalyst. This method allows for the synthesis of a variety of functional biaryls using inexpensive catalysts. It was noted that 10 mol% of the ligand, (diphenylphosphino)propane was needed to increase the yields of the borylation reaction.
