Yield:-
Reaction Conditions:
with palladium(II) trifluoroacetate;toluene-4-sulfonic acid;DPEPhos in tetrahydrofuran at 30; under 150015 Torr;Inert atmosphere;
Steps:
2 Example 2
Measure 30mmol of 2-butene, 0.15mmol of p-toluenesulfonic acid, 15mmol of bis(2-diphenylphosphinephenyl)ether, 15mmol of palladium trifluoroacetate, 3ml of ethanol and 27ml of tetrahydrofuran, and add them together to a 100ml reaction kettle, and use Nitrogen was replaced three times, and CO was replaced three times, filled with 20MPa CO, stirred and reacted at 30°C for 24 hours, cooled, added internal standard (1-hexanol) 10mmol, analyzed by gas chromatography, the conversion rate of 2-butene was 92 %, the selectivity of valerate is 96%.
