Palladium- or Nickel-Catalyzed Coupling Reaction of Dialkoxyboranes with Chloroarenes: Arylation of 1,3,2-Dioxaborolanes or 1,3,2-Dioxaborinanes
摘要:
The borylation of electron-deficient aryl chlorides with pinacolborane proceeded in the presence of Bu4NI and a catalytic amount of Pd(dba)(2) / bis(2-di-tert-butylphosphinophenyl) ether. The combination of NiCl2(dppp) catalyst and Bu4NBr was also efficient for the borylation of aryl chlorides.
