Patent ID: 7781599

Claim:
A process for production of an aromatic compound represented by formula (1) below: R-A (1) wherein, R is an optionally substituted hydrocarbon group or a C 3 -C 10 saturated or unsaturated ring group, which ring may optionally be intervened by an oxygen atom or a group represented by formula —N(B)— (wherein B is a hydrogen atom, an optionally substituted C 1 -C 10 hydrocarbon group or an optionally substituted C 1 -C 10 alkoxycarbonyl group) and may optionally be substituted; with the proviso that an aromatic group or a heteroaromatic group is excluded from R; and A is an optionally substituted C 4 -C 20 aromatic group or an optionally substituted heteroaromatic group, which comprises reacting a compound represented by formula (2) below: R—X (2) wherein, R has the same significance as defined above, and X is a halogen atom or a sulfonic acid ester, with an aromatic magnesium reagent represented by formula (3a) below: A-Mg—Y 1 (3a) wherein A has the same significance as defined above and Y 1 is bromine, iodine, chlorine or a carbanion ligand, in the presence of an iron catalyst and a diamine compound.
