Base and Cation Effects on the Suzuki Cross-Coupling of Bulky Arylboronic Acid with Halopyridines: Synthesis of Pyridylphenols. -Strong base and large size cation are shown to accelerate the rate and yield of Suzuki coupling of sterically bulky boronic acid with halopyridines. Best results are obtai

## Abstract We report here the transition‐metal‐catalyzed chemoselective cross‐coupling of arylbroronic acids in high yields without using ligand or base. We have developed an efficient copper‐catalyzed protocol for the homocoupling and cross‐coupling of arylboronic acids. The protocol is also suit
