LIGAND, METAL COMPLEX CONTAINING LIGAND, AND REACTION USING METAL COMPLEX CONTAINING LIGAND

摘要

A hydrogen transfer reaction may be more efficiently promoted by using a metal complex represented by Formula (2): (wherein, R 1 to R 8 are the same or different, and each represents a hydrogen atom, a substituted or unsubstituted alkyl group or the like; or wherein; R 1 and R 2 , R 2 and R 3 , R 3 and R 4 , R 4 and R 5 , and R 5 and R 6 are respectively bonded to each other to form a bivalent hydrocarbon group; R 9 are the same or different, and each represents an alkyl group or cycloalkyl group; M is ruthenium (Ru) or the like; X is a ligand; and n is 0, 1 or 2). More specifically, the metal complex enables a hydrogenation reaction of various substrates having a stable carbonyl group or the like to be advanced with a high yield under mild conditions.
