Abstract
A new mixed-valent Rh2II,III dimer, [Rh2(espn)2Cl] (espn2− = α,α,α′,α′-tetramethyl-1,3-benzenedipropanamidate), is reported. This compound readily dissociates Cl− at low concentrations in solution to form the active [Rh2(espn)2]+catalyst, which performs intramolecular C–H amination with TONs > 1400. This work expands the scope of Rh2II,III dimers to nitrenoid chemistry.
