The catalytic conversion of benzole anhydrides into fluorenones and biphenyls by several rhodium compounds has been studied. Mixtures of aromatic anhydrides react generally as if they were mixed anhydrides, leading to the formation of asymmetrically substituted products. Equimolar amounts of the isolated phenyl-rhodium complex PhRhCl(PPh3)2 (7) and chlorocarbonylbis(triphenylphosphine)rhodium (2) react at 250° to give fluorenone and biphenyl. Both these compounds are assumed to be formed via the same rhodium intermediate.
