Novel compound 1,2-di(isobutylphenyl)ethane and method for preparing 4-isobutylstyrene and a-(4-isobutylphenyl)propionic acid from this compound. In the preparation of 4-isobutylstyrene from the former compound by cracking or disproportionation, the components in the resultant reaction mixture can be separated without difficulty, the formation of by-product isobutylbenzene can be avoided, and the remaining unreacted starting material can be reused for the same reaction without causing any adverse effect on the catalyst.
