-

Yield:503-74-2 99.1%

Reaction Conditions:

with potassium acetate;palladium diacetate;C34H36O8 at 30 - 35; for 6 h;Catalytic behavior;Inert atmosphere;Reagent/catalyst;

Steps:

7-12 Example 7

General procedure: To a dry 1L three-neck flask, add isovaleraldehyde (160g, 1.86mol), isovaleric acid (160g, 1.57mol), the above ligand L2 (24.8mg, 0.04mmol), palladium acetate (44.9mg, 0.2mmol) ) And potassium acetate 260mg; mechanically stirred under a nitrogen atmosphere, after the temperature rises to 30°C, start to pass in air at a flow rate of 19.8g/h, and keep the reaction temperature between 3035°C by adding cooling water to the water bath Reaction in any range, after 8h reaction, isovaleric acid is prepared.
