[摘要]:Efficient cross-coupling reactions of aryl bromides with AlArEt2(THF) (Ar = Ph, 4-MeC6H4, 4-MeOC6H4, 4-Me3SiC6H4, or 2-naphthyl) catalyzed by a catalytic system of 1 mol% Pd(OAc)(2) and 2 mol% PCy3 furnish aryl-aryl coupling products. The system works well for a wide range of aryl bromides regardless of the electronic or steric nature of the substituent on the aryl bromides. |
