Manganese(iii) complexes stabilized with N-heterocyclic carbene ligands for alcohol oxidation catalysis

Abstract

The chemistry of N-heterocyclic carbenes with Earth-abundant manganese has largely focused on low-valent systems for reductive catalysis. Here, we have decorated imidazole- and triazole-derived carbenes with phenol substituents to access...

Application of first-row transition metal complexes bearing 1,2,3-triazolylidene ligands in catalysis and beyond

“…Thus, reacting ligand precursor L9 with [Mn(acac) 3 ] and KO t Bu, results in the formation of the paramagnetic complex Mn12 ( Scheme 12a ). 83 The crystal structure reveals coordination of the tridentate pincer ligand and a bidentate acac ligand. The square pyramidal geometry is significantly more distorted ( τ 5 = 0.47) compared to the analogue featuring an imidazolylidene donor ( τ 5 = 0.18).…”
