Abstract

The new N,N,O ligand 2,2-bis(3,5-dimethylpyrazol-1-yl)propionic acid (2,2-Hbdmpzp) (2) and its transition metal complexes [Mn(2,2-bdmpzp)(CO)3] (3), [Re(2,2-bdmpzp)(CO)3] (4), [Cu(2,2-bdmpzp)2] (5), and [Ru(2,2-bdmpzp)Cl(L)(PPh3)] [L = PPh3 (6), N2 (7), CO (8a/b), SO2 (9a/b)] have been synthesized, characterized and compared to analogous complexes bearing a bis(3,5-dimethylpyrazol-1-yl)acetic acid. It was found that the additional methyl group has a remarkable influence on the stability and reactivity of transition metal complexes.
