Phenalenyl-based copper complex catalyzed direct biarylation of furan

Abstract

In this work, a newly designed phenalenyl (PLY)-based copper-bipyridine (BPY) heteroleptic system of the form [(BPY)Cu^II(PLY)Cl] has been introduced as a cheap and effective catalytic system for the biarylation of furan using aryldiazonium salts. The crucial function of each unit of [(BPY)Cu^II(PLY)Cl] in this catalytic reaction was determined through a combination of structural, electrochemical, spectroscopic, theoretical, and mechanistic studies.
