Reaction Conditions:
with caesium carbonate in water at 20;
Steps:
2.4. Procedure for synthesis of β-aryl enals and enones
General procedure: The β-aryl enals were synthesized by the following procedure.In a 50 mL round bottom (RB) flask, 2 mmol of benzaldehyde,9 mL ethanol (CH3CH2OH) and 3 mL water (H2O) was added in astoichiometric ratio of 3:1. After this, 2 equivalents of cesiumcarbonate (Cs2CO3) were added to the above mixture along with 25 mg of the synthesized CoCr2O4-HNT catalyst. The whole mixturewas then refluxed at 120 °C for 8 h. The reaction was monitoredthrough thin layer chromatography (TLC) and the productswere isolated through chromatography separation. Similarly, in a 50 mL RB flask b-aryl enones were synthesized bytaking the same amount of the substrate using 20 mg of CoCr2O4-HNT and in 1:3 ratio of H2O and ipr-OH (3 mL H2O + 9 mL ipr-OH).The reaction was stirred at room temperature for 4 h. After 4 h, thecatalyst was separated by normal filtration and the products wereseparated by chromatographic technique.
