Access to functionalized luminescent Pt(ii) complexes by photoredox-catalyzed Minisci alkylation of 6-aryl-2,2′-bipyridines

Abstract

Photoredox-mediated C–H bond alkylation of 6-aryl-2,2′-bipyridines with N-(acyloxy)phthalimides is reported. The reaction exhibits excellent functional group tolerance, including chiral aliphatic groups. The influence of the incorporated C6′-alkyl group on the photophysical properties of the corresponding (N^N^C) cyclometalated Pt(II) complexes is described, including chiroptical properties.
