The invention relates to a composition comprising a mixture of alkylated N-α-naphthyl-N-phenylamine (PANA) and alkylated diphenylamine (DPA), the product obtainable by alkylating PANA or a mixture of PANA and DPA with alkenes and the process for alkylating PANA or a mixture of PANA and DPA with alkenes. The compositions according to the present invention have an outstanding anti-oxidative action, which can be demonstrated by established test methods.

were observed directly and that undergo migratoryinsertion, followed by β-hydride elimination to generate enamine products. The effect of the steric properties of the ancillary ligand on the binding of the alkene and the rate of migratoryinsertion were evaluated individually. The relative binding affinity of ethylene vs THF is larger for the less sterically hindered complex than for the more hindered
