Abstract
3-Benzenepropanal as an important perfume was successfully synthesized by the reduction-hydrolysis reaction of 1,3-dimethyl-2-(2-phenylethyl)-benzimidazolium iodide with sodium/ethanol,wherein 1,3-dimethyl-2-(2-phenylethyl)-benzimidazolium iodide can be obtained from o-diaminobenzene and 3-benzenepropanoic acid.The reaction conditions for synthesis of 3-benzenepropanal were studied and its mechanism was discussed.A novel convenient method for preparing perfume aldehydes from carboxylic acids has been thereby provided.
