1. A method for producing a multisubstituted biphenyl compound represented by the following formula (2), comprising:
a step of coupling a substituted benzene compound represented by the following formula (1) in the presence of a solid catalyst with gold immobilized onto a support, wherein R represents an alkyl group, an alkoxy group, a hydroxy group, or a carboxyl group which may be esterified, and n represents an integer of 0 to 3; when n is any integer of 1 to 3, a plurality of R may be the same or different from each other; and when n is any integer of 1 to 3 and both of two R bonding to adjacent carbon atoms are the carboxyl groups, these carboxyl groups may bond to each other to form an anhydride, and wherein R represents an alkyl group, an alkoxy group, a hydroxy group, or a carboxyl group which may be esterified, and n represents an integer of 0 to 3; a plurality of n and R may be the same or different from each other; and when n is any integer of 1 to 3 and both of two R bonding to adjacent carbon atoms are the carboxyl groups, these carboxyl groups may bond to each other to form an anhydride.
