Abstract
Imine N^N^C-type pincer ligands were reacted with palladium(II) acetate and palladium(0) bis(dibenzylideneacetone) and the regioselective C–H and C–X activation was studied. C–X bonds that formed six-membered rings were selectively activated over C–H bonds; in addition sp2 C–H bonds were selectively activated over sp3 CH bonds. The formation and regioselectivity of the cyclometalated palladium(II) complexes were characterized by NMR, MS, and XRD. Photoluminescence studies of cyclopalladated complexes were conducted.
