Method for producing aromatic compound

A method for producing an aromatic compound represented by the following formula (3):

• Ar1Ar2)n (3)
• wherein Ar1, Ar2 and n are the same as defined in formulae (1) and (2),
• which comprises subjecting an aromatic nitro compound represented by the following formula (1):
• Ar1NO2)n (1)
• wherein Ar1 is an aromatic hydrocarbon group which may have a substituent or a heteroaromatic group which may have a substituent, and n is an integer of from 1 to 5;
• and a boronic acid compound represented by the following formula (2):
• Ar2—B(OR1)2 (2)
• wherein Ar2 is an aromatic hydrocarbon group which may have a substituent, or a heteroaromatic group which may have a substituent, R1 is each independently a hydrogen atom, a C1-4 alkyl group or a phenyl group, and the two R1 substituents may be linked to form a ring containing oxygen atoms and a boron atom;
• to a cross coupling reaction in the presence of a palladium or nickel compound as a transition metal catalyst.
