A relationship between substituents on the aryl ring undergoing homolytic aromatic substitution and the yield of Pschorr reaction product has been demonstrated.The new variation in which a (phenylsulfonyl)oxy group is present on the acceptor ring has been used to synthesize several highly oxygenated 9-phenanthrenecarboxylic acids in significantly improved yields.
