ABSTRACT:
An improvement in the process for alkylating the nucleus of an aromatic amine which contains small amounts of a nickel compound by reaction with an olefin in the presence of an aluminum anilide-type catalyst whereby hydrogen sulfide or a sulfide generating compound (e.g. thioacetamide) is added to the aromatic amine to reduce the rate inhibiting effect of the nickel compound.
