摘要:
A 3,3′,4,4′-tetraalkyl cyclohexylbenzene represented by the general formula (1): in which R represents an alkyl group having 1 to 4 carbon atoms, which may be easily converted into a 3,3′,4,4′-biphenyltetracarboxylic acid and a 3,3′,4,4′-biphenyltetracarboxylic dianhydride thereof, which are starting materials for a polyimide, via a 3,3′,4,4′-tetraalkylbiphenyl; and a method for producing the same.
