A green protocol for the Pd catalyzed ligand free homocoupling reaction of arylboronic acids under ambient conditions

Abstract

A simple, competent, green pathway has been developed for the Pd catalyzed ligand free homocoupling reaction of arylboronic acids in water under ambient conditions. An efficient reaction environment is generated using a combination of Pd(OAc)₂ and ‘green additives’, which exhibited excellent activity and results in high yields of the desired coupled products within 15 minutes.
