A method for preparing metal complexes with tris (alkyl imidazole - 2 - ylidene) borato - ligands and their use in the homogeneous catalysis

摘要

Producing metal complexes with tris-(3-alkylimidazol-2-ylidene)-borato ligands of formula (1), comprises reacting the corresponding tris-imidazolyl-borate with a base and a transition metal in aprotic solvent or in aqueous medium.
