The catalytic organic-hydride transfer to CO2 was first achieved through the photoinduced two-electron reduction of the [Ru(bpy)2(pbn)]2+/[Ru(bpy)2(pbnHH)]2+ (bpy = 2,2'-bipyridine, pbn = 2-(pyridin-2-yl)benzo[b]-1,5-naphthyridine, and pbnHH = 2-(pyridin-2-yl)-5,10-dihydrobenzo[b]-1,5-naphthyridine) redox couple in… Click to show full abstract
The catalytic organic-hydride transfer to CO2 was first achieved through the photoinduced two-electron reduction of the [Ru(bpy)2(pbn)]2+/[Ru(bpy)2(pbnHH)]2+ (bpy = 2,2'-bipyridine, pbn = 2-(pyridin-2-yl)benzo[b]-1,5-naphthyridine, and pbnHH = 2-(pyridin-2-yl)-5,10-dihydrobenzo[b]-1,5-naphthyridine) redox couple in the presence of 1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]imidazole (BIH). The active species for the catalytic hydride transfer to carbon dioxide giving formate is [Ru(bpy)(bpy•-)(pbnHH)] + formed by one-electron reduction of [Ru(bpy)2(pbnHH)]2+ with BI•.
