Abstract
Metalation of C6H6 has been known for a long time as a side reaction occurr ing in refluxing benzene solutions of Rh-2(CO)(4)(TPP) (TTP = tetraphenylpo rphyrin). Rather than representing the intrinsic reactivity of this complex , such hydrocarbon activation proceeds via Rh-II(por) and Rh-III(por) deriv atives resulting from oxidation of Rh-2(CO)(4)(TPP) with adventitious H2O a nd/or O-2. This reaction can be extended to other aromatic substrates and r epresents an efficient synthetic route to certain organometallic Rh-III(TPP ) derivatives. [GRAPHICS]
