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

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 corre...

More Information
Summary: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. Photoredox catalysis is employed to design unprecedented C6′-functionalized 6-aryl-2,2′-bipyridines to prepare (circularly polarized) luminescent cyclomatalated platinum( ii ) complexes.
