A practical nickel-catalyzed protocol for the synthesis of sterically hindered 9-arylacridines via Negishi type cross-coupling was developed. The method enables a convenient approach to a set of active acridine photocatalysts starting from commercially available 9-chloroacridine, inexpensive catalyst [NiCl2(Ph3P)2], and organozinc reagent with no need for additional ligands and precious metals. The
