Bis(dinitrogen)bis<1,2-bis(diphenylphosphino)ethane>molybdenum reacts with chlorobenzene to form molybdenum chloro complexes and phenylated organic products.Benzene, biphenyl, o-, m-, p-chlorobiphenyl, a dihydro derivative of o-chlorobiphenyl, triphenylphosphine and diphenylvinylphosphine were formed.The isomer distribution of the chlorobiphenyls is close to that obtained by decomposition of 0.02 M benzoyl peroxide in chlorobenzene under dinitrogen.The cleavage of the Ph-Cl bond induced by the molybdenum-dinitrogen complex appears to give rise to the same homolytic reaction pattern.Phenylation of anisole and of triethyl phosphite has also been achieved with the same reagent.
