Introducing a mixed-valent dirhodium(II,III) catalyst with increased stability in C–H amination

Author affiliations

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.
