Reaction Conditions:
with copper(II) nitrate trihydrate in water;acetonitrile at 130; for 12 h;
Steps:
14 Example-14
Add 0.3 mmol of isopropyl cinnamaldehyde and 0.45 mmol of copper nitrate trihydrate to a 15 mL pressure tube, and then add 3 mL of a mixture of acetonitrile and water (V (acetonitrile): V (water) = 100:1) as solvent . Next, stirring was performed at 130° C. (magnetic stirring for 12 hours). Then, two shots of column chromatography silica gel (100-200 mesh) was added to the reaction solution, and the solvent was removed by distillation under reduced pressure. The residue was separated by column chromatography. Using a mixture of V (petroleum ether):V (ethyl acetate) = 20:1 as eluent, the eluent containing the target product was collected, and the solvent was distilled off to obtain pure product. The amount of pure product was: 0.216 mmol The material was a yellow solid, chemical name 2-nitro-p-isopropylstyrene, yield 72%.
