Protic Ruthenium Tris(pyrazol-3-ylmethyl)amine Complexes Featuring a Hydrogen-Bonding Network in the Second Coordination Sphere
We synthesized ruthenium complexes bearing a tris(pyrazol-3-ylmethyl)Amine ligand 1,113 and revealed that this tripodal ligand allows predictable accumulation of three proton-delivering NH groups around a coordination site. The Bronsted acidity of the NH groups in LH3 led to the formation of multiple hydrogen bonds With the substrate ligand and deprotonalion. The chlorido complex ligated by LH3 catalyzed disproportionation of 1,2:diphenylhydrazine.
