Electronic Structures and Reactivity Profiles of Aryl Nitrenoid-Bridged Dicopper Complexes.

ABSTRACT: Dicopper complexes templated by dinucleating, pacman dipyrrin ligand scaffolds (^Mesdmx, ^tBudmx: dimethylxanthine-bridged, cofacial bis-dipyrrin) were synthesized by deprotonation/metalation with mesitylcopper (CuMes; Mes: mesityl) or by transmetalation with cuprous precursors from the corresponding deprotonated ligand. Neutral imide complexes (^Rdmx)Cu₂(μ²-NAr) (R: Mes, ^tBu; Ar: 4-MeOC₆H₄, 3,5-(F₃C)₂C₆H₃) were synthesized by treatment of the corresponding dicuprous complexes with aryl azides. While one-electron reduction of (^Mesdmx)Cu₂(μ²-N(C₆H₄OMe)) with potassium graphite initiates an intram
