| With C18H28Br2N4Ru; potassium tert-butylate; hydrogen In 1,4-dioxane at 105℃under 22502.3 Torrfor 8h; | A n/a B 94% |
| With C30H37ClN4ORu; hydrogen; sodium t-butanolate In toluene at 105℃under 4500.45 Torrfor 20hReagent/catalystGloveboxSealed tubeOverall yield = 98 percent; Experimental Procedure General procedure: To a mixture of catalyst (0.01 mmol), KOtBu (10 mol %), and 1,4-dioxane (4.0 mL) in a Parr high-pressure reactor was added the ester(1.0 mmol). The dark red solution was purged with H2 and stirred under 400 psi of H2 at 105 °C for 8 h. Products isolation were performed via column chromatography using silica gel as stationary phase and n-pentane/ethylacetate or n-pentane/isopropanol mixture as eluent. The products were confirmed by 1H NMR. | A n/a B 92% |
