PBD was converted into 4'-substituted derivatives I-XII using usual electrophilic reagents.The decompositions of PBD, 4'-acetyl derivative I and 4'-nitro derivative VI with hydroiodic acid gave 4'-substituted 4-biphenylcarboxylic acids XIIIa-XIIIc and benzoic acid, respectively.The regioselectivity of the reactions was also proved by means of high resolution NMR spectroscopy.
