Significance

A nickel-based catalytic system for the arylation of heteroarenes with aryl halides and triflates is reported herein. While aryl bromides and iodides are readily coupled using Ni(OAc)2/bipy, Ni(OAc)2/dppf is effective for aryl chlorides or triflates. The coupled products are obtained in good to very good yields and the authors make use of this procedure in a rapid synthesis of febuxostat, a drug for hyperuricemia and gout.
