Yield:-

Reaction Conditions:

with dihydrogen peroxide at 60; for 3 h;

Steps:

2.3. Catalytic reaction
General procedure: The catalytic reactions were performed in a round-bottomed flask equipped with a magnetic stirring bar and a reflux condenser. The oxidative esterification was carried out as follows: catalyst (20 mg), aldehyde (1 mmol) and alcohol (5 mmol) were magnetically stirred in the reaction flask at 60 °C. H2O2 (2 mmol) was progressively added to the reaction mixture using a syringe. The reactions were stopped after 3 h and the excess hydrogen peroxide was deactivated by the addition of aq. sodium bisulfite. The catalyst was separated from the reaction mixture by filtration. As a two-layer mixture was obtained (organic phase/water phase) after the reaction, the organic products were separated from the aqueous phase by ethyl acetate extractions. The combined organic layers were washed with brine and dried over anhydrous Na2SO4, and then analyzed by GC-MS.
