Reaction Conditions:
with G/MFSiO2Cu(proline)2 at 20; for 5 h;Green chemistry;
Steps:
Aldol reactions catalyzed by G/MFSiO2Cu(proline)2
General procedure: A mixture of benzaldehyde and cyclohexanone at molar ratio of 1:2 mmol and nanocatalyst(0.1 g) was stirred at 40-60 °C; the progress of the condensation reactionwas monitored continuously by thin-layer chromatography (TLC). Ethyl acetate(10 mL) was then added to the reaction mixture, and the nanocatalyst was magneticallyseparated and washed with ethyl acetate and dried for reuse in a new aldolreaction. The remaining liquid was washed with saturated aqueous sodium chloridesolution (5 mL) and water (10 mL). The organic layer, which contains the productof the aldol reaction, was separated and dried over anhydrous Na2SO4,followedby evaporation of the solvent at room temperature. The remaining residue was thenrecrystallized in ethanol to give pure aldol product with 98 % yield. The yields inthis and other similar reactions were measured by GC analysis. Identification of theproducts for a number of selected reactions between cyclohexanone and benzaldehydederivatives was also performed by 1H NMR and GC-mass spectrometry (MS)techniques. The spectral data of selected products are given below.
