Abstract
Modification of Rh/C with Re species enabled chemoselective hydrogenolysis of tetrahydropyran‐2‐methanol to 1,6‐hexanediol. In particular, the Rh–ReOx/C (Re/Rh ratio=0.25) catalyst gave a high yield of 1,6‐hexanediol (84 %) and showed a very low activity for overhydrogenolysis to 1‐hexanol. Using the same catalyst in the hydrogenolysis of tetrahydrofurfuryl alcohol also gave a high yield of 1,5‐pentanediol (94 %). Characterization results indicate the formation of ReOx clusters attached on the surface of Rh metal particles. This can cause the synergy between ReOx and Rh, and the tetrahydropyran‐2‐methanol hydrogenolysis proceeds on the interface between Rh metal surface and attached ReOx species.
