Synthesis and characterization of copper and nickel complexes with N-arylpyrrole-2-aldimines
摘要:
A series of 17N-arylpyrrole-2-aldimine ligands has been synthesized by condensation of pyrrole-2-carboxaldehyde and substituted anilines. All CuL2 complexes are square, whereas NiL2 compounds are square, tetrahedral or eventually present a square half arrow right over half arrow left tetrahedral equilibrium. Attempts of chemical oxidation have shown the existence of nickel(III) and copper(III) in solution.
