A catalytic process having more than 50 turnovers comprising thermally activating said catalyst in the presence of a functionalizing reagent and a cyclic hydrocarbon comprising an aromatic compound or a cycloparaffin compound lacking primary C-H bonds, said catalyst comprising:
a) a source of a transition metal;
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 the transition metal a) and which dissociate thermally;
and wherein said functionalizing reagent comprises a source of B, C, N, O, Si, P, S, Ge, As, Al, or Se.
