ABSTRACT:
The present invention mainly relates to a carbon-carbon bond formation catalyzed by a complex comprising a novel and stable ligand and a metal center. The ligand uses a ring, particularly a phenyl group, or a hydrocarbon group to link an amino group and PR1R2, NR1R2, OR1, SR1, or AsR1R2group for stabling the structure of the ligand.
