METHOD FOR ALKYLATING AROMATIC RING COMPOUNDS WITH ALKANES

摘要

The invention concerns a method for performing one or several aromatic substitutions on a compound (A) comprising at least an aromatic ring, which consists in grafting an alkyl fragment on the aromatic ring of a compound (A) by reacting said compound (A) with one or several linear or branched alkanes or linear or branched alkyl chains (B) having more than two carbon atoms, in the presence of a catalyst based on a metal M capable of catalyzing an alkane metathesis reaction. The catalyst preferably comprises a metal M-hydrocarbyl complex, optionally in hydride form, in particular grafted and dispersed on a solid support. The metal M can be selected among transition metals, lanthanides and actinides.
