Reaction Conditions:

with rhodium(III) chloride;ethanol at 140 - 145;

Steps:

2 (2) isomerization of eugenol: the isomerization reaction of eugenol by preparing isoeugenol

In a 25 ml flask was added4.2 mg of rhodium trichloride (RhCl3),And add about 3 drops of absolute ethanol to dissolve,Then 20.0 mmol (3.284 g)The eugenol obtained in step (1)The reaction at 140-145 ° C for 3-5h,The reaction liquid gradually changed from pale yellow to bright orange then dark orange,Detection of each section of the reaction liquid,Structural analysis with UV - Vis spectroscopy,After the reaction, stop heating,Cooled to room temperature; suction filtered,Rhodium trichloride catalyst was separated and recovered; Extraction of isoeugenol in the filtrate with ether,The combined organic layers,Evaporate the ether in the water bath,Get isoeugenol,The yield of isoeugenol is about 99%;
