A process for functionalizing a cyclic hydrocarbon at a secondary or aromatic C-H cyclic hydrocarbon bond comprising thermally reacting a functionalizing reagent and the cyclic hydrocarbon in the presence of a catalyst, said catalyst comprising: a) a source of rhodium; b) a source of a 3 to 8, cyclic or non-cyclic, aromatic or non-aromatic, neutral, cationic or anionic, substituted or unsubstituted, electron donor moiety which does not dissociate under thermal reaction conditions; and c) a source of ligands capable of formally donating an electron pair to rhodium and which dissociate thermally; and wherein said functionalizing reagent comprises a source of boron.

L'invention concerne un procédé permettant de fonctionnaliser un hydrocarbure cyclique en une liaison hydrocarbure cyclique C-H secondaire ou aromatique comportant la réaction thermique d'un réactif de fonctionnalisation et de l'hydrocarbure cyclique en présence d'un catalyseur, ledit catalyseur comprenant : a) une source de rhodium; b) une source comprise entre 3 et 8 d'une fraction de donneur d'électrons cyclique ou non-cyclique, aromatique ou non-aromatique, neutre, cationique ou anionique, substituée ou non-substituée, qui ne se dissocie pas en conditions de réaction thermique; et c) une source de ligands capable de donner formellement une paire d'électrons au rhodium et qui se dissocient thermiquement; et dans laquelle ledit réactif de fonctionnalisation comprend une source de bore.
