Title:
CATALYST FOR COUPLING AND LIGAND USED FOR THE SAME AND METHOD FOR PRODUCING COMPOUND HAVING BIARYL STRUCTURE BY CROSS COUPLING REACTION
Document Type and Number:
Japanese Patent JP2008247881
Kind Code:
A
Abstract:
To provide a new phosphine compound for a ligand of a catalyst useful for cross coupling reaction and its metal complex.
The phosphine compound is represented by formula (I) (R1 and R2 are each a cycloalkyl group or the like; n is 1-3 and m is an integer of 1 or 2). A Pd metal complex comprises the phosphine compound as a ligand. In a method for producing a compound having a biaryl structure by carrying out cross coupling of an aromatic compound with a Grignard reagent, the reaction is carried out in the presence of the metal complex.
