Nanoreactors encapsulating homogeneous catalysts behave as heterogeneous catalysts at the macroscopic scale, enabling the homogeneous catalyst to be easily recovered. One way to synthesize such nanoreactors is by inserting the homogeneous catalyst (or synthesizing it in situ) in the porosity of an inorganic oxide material, followed by a silylation reaction to narrow the pore entrance, preventing the outwards diffusion of the jailed homogeneous catalyst during the reaction. This way, the often-superior activity of homogeneous catalysts is combined with the robustness and the easy recovery of heterogeneous ones. Hereunder, we report for the first time the implementation of such a strategy towards the synthesis of a deoxydehydration (DODH) catalyst, namely a bis-amino phenol Re-complex. 1,2-hexanediol was used as the DODH vicinal diol model substrate. The encapsulation of the homogeneous catalyst in SBA-1 was demonstrated. It proved active in the DODH test reaction although not sustainably; the deactivation mechanism was therefore elucidated.
