Diborane Reductions of CO₂ and CS₂ Mediated by Dicopper μ-Boryl Complexes of a Robust Bis(phosphino)-1,8-naphthyridine Ligand.

ABSTRACT: A dinucleating 1,8-naphthyridine ligand featuring fluorene-9,9-diyl-linked phosphino side arms (PNNP^Flu) was synthesized and used to obtain the cationic dicopper complexes 2, [(PNNP^Flu)Cu₂(μ-Ph)][NTf₂]; [NTf₂] = bis(trifluoromethane)sulfonimide, 6, [(PNNP^Flu)Cu₂(μ-CCPh)][NTf₂], and 3, [(PNNP^Flu)Cu₂(μ-O^tBu)][NTf₂]. Complex 3 reacted with diboranes to afford dicopper μ-boryl species (4, with μ-Bcat; cat = catecholate and 5, with μ-Bpin; pin = pinacolate) that are more reactive in C(sp)-H bond activations and toward activations of CO₂ and CS₂, compared to dicopper μ-boryl complexes supported b
