a Results for the isomerization of 1 with different Ru–supported solid catalysts. Ru–KY refers to zeolite NaY exchanged with K+ and then with Ru3+. The Ru wt% on each solid is indicated between brackets, mol% refers to the catalytic amount of Ru in reaction. b Reuses of Ru–KY. c Hot filtration leaching test for commercial Ru–Al2O3. d Hot filtration leaching test and reuse of Ru–SiO2. The supported Ru catalysts are either commercial (entry 4 and 5) or in–house prepared by impregnation of aqueous RuCl3 (entry 1–3 and 6). The optimized amount of catalyst is shown for each solid. Error bars account for a 5% uncertainty.
