Oxidation of the tris(carbene)borate complex PhB(MeIm)(3)Mn-I(CO)(3) to Mn-IV[PhB(MeIm)(3)](2)(OTf)(2)
Reaction of the tris(carbene)borate ligand PhB(MeIm)(3)(-) with [Mn(CO)(3)((BuCN)-Bu-t)Br](2) leads to the manganese(I) tricarbonyl complex PhB(MeIm)(3)Mn(CO)(3). In contrast to related complexes that are air-stable, PhB(MeIm)(3)Mn(CO)(3) is O-2-sensitive and is converted to a homoleptic Mn-IV complex. IR and cyclic voltammetry measurements of these complexes establish the exceptionally strong donating nature of the tris(carbene)borate ligand.
