Ether-imidazolium carbenes for Suzuki-Miyaura cross-coupling of heteroaryl chlorides with aryl/heteroarylboron reagents

Org Lett. 2013 Jun 7;15(11):2716-9. doi: 10.1021/ol4010189. Epub 2013 May 28.

Abstract

Easily accessible and handled ether-imidazolium chlorides were developed as ligand precursors. The coupling reactions of heteroaryl chlorides with aryl/heteroarylboronic acids and esters were catalyzed by the palladium/ether-imidazolium chloride system with high substrate tolerance to give various heterobiaryls in good to excellent yields.
