Patent ID: 8143407

Claim:
A process of producing a heteroaryl boron compound of formula (VIII) or (IX): wherein, u, v, w, R 4 and R 5 are the same as defined below, comprising: reacting an aromatic heterocyclic compound of formula (VII) with a boron compound of formula (III) or (IV) in the presence of an iridium-containing catalyst of formula (X) and a ligand: wherein u, v and w are each independently —CH═ or —N═, and R 4 and R 5 are each independently a hydrogen atom, a linear or branched C 1-8 alkyl group, a linear or branched C 1-8 alkoxy group, a nitro group, a cyano group, a halogenated C 1-8 alkyl group, a halogen atom, a carbamoyl group, a C 1-8 acyl group, a C 1-8 alkoxycarbonyl group, an optionally substituted amino group, or formula (II) in which R 4 and R 5 are adjacent and form a ring: wherein, R 3 is a hydrogen atom, a linear or branched C 1-8 alkyl group, a linear or branched C 1-8 alkoxy group, a nitro group, a cyano group, a halogenated C 1-8 alkyl group, a halogen atom, a carbamoyl group, a C 1-8 acyl group, a C 1-8 alkoxycarbonyl group or an optionally substituted amino group: IrABn (X): wherein, A is an anion portion and B is an alkene portion.
