Abstract
PURPOSE:To obtain a biphenyl compound in high yield, by carrying out dehalogenative dimerization of an aromatic compound having halogen on aromatic carbon in the presence of a Pd catalyst, water, amino alcohols and a halogen acceptor. CONSTITUTION:A biphenyl compound is produced by reacting an aromatic compound having halogen on aromatic carbon atom (e.g. chlorobenzene) in the presence of a Pd catalyst (especially Pd-activated carbon), water, amino alcohols and a halogen acceptor at 50-200 deg.C under normal pressure -100kg/cm<2> for 10min-24hr. The amino alcohols are those having OH and NH2 bonded to adjacent C atoms (e.g. monoethanolamine) and are used in an amount of 0.5-10mol per 1mol of the raw material. The halogen acceptor is preferably an alkali or alkaline earth metal compound (preferably hydroxide) and is used in an amount of preferably 0.1-20mol per 1mol of the raw material.
