LIGAND, NICKEL COMPLEX COMPRISING LIGAND, AND REACTION USING NICKEL COMPLEX

PROBLEM TO BE SOLVED: To provide a method for directly carrying out arylation, especially α-arylation, of a carbonyl compound or a thiocarbonyl compound by using a more inexpensive phenol derivative and a nickel catalyst, and to provide a novel nickel cat

Nickel-catalyzed α-arylation of ketones with phenol derivatives

The nickel-catalyzed α-arylation of ketones with readily available phenol derivatives (esters and carbamates) provides access to useful α-arylketones. For this transformation, 3,4-bis(dicyclohexylphosphino) thiophene (dcypt) was identified as a new, enabling, air-stable ligand for this transformation. The intermediate of an assumed C-O oxidative addition was isolated and characterized by X-ray crystal-structure analysis.
