Yield:36653-82-4 98%

Reaction Conditions:

with C32H36ClNO2P2Ru;potassium tert-butylate;hydrogen in tetrahydrofuran at 120; under 38002.6 Torr; for 20 h;Autoclave;Green chemistry;

Steps:

56 Example 48: Hydrogenation of methyl benzoate catalyzed by two thousandths of a molar equivalent of ruthenium complex 1c

General procedure: In a glove box in a nitrogen atmosphere, 3.33 mg of ruthenium complex 1c (0.005 mmol) Add to a 125-mL Parr autoclave, After adding 11.2 mg of potassium t-butoxide (0.1 mmol), Then take 2mL of tetrahydrofuran and add it to the kettle for a while. Finally, methyl benzoate (1.3615 g, 10 mmol) was added. After the autoclave is sealed, it is taken out of the glove box. Charge hydrogen to 50 atm. The mixture in the reaction kettle was heated and stirred in an oil bath at 120 ° C for 10 hours, The reactor was cooled to room temperature in a water bath and the remaining gas was slowly drained from the fume hood. Tridecane (50 μL) was added to the mixture as an internal standard, and the yield of methyl benzoate was determined by gas chromatography to be 99%.
