Cobalt-phenanthroline catalysts for the ortho alkylation of aromatic imines under mild reaction conditions

Research output: Contribution to journalArticlepeer-review

Abstract

Mild mannered: Cobalt catalysts complexed with phenanthroline-type ligands and activated with Grignard reagents serve as inexpensive and effective catalysts for the ortho alkylation of aromatic imines with a variety of olefins (see scheme). The new catalytic systems feature remarkably mild reaction conditions for C-H bond activation and functionalization.
