摘要

Abstract

A facile and efficient procedure has been developed systematically for the oxidative cleavage of cinnamaldehyde to benzaldehyde by sodium hypochlorite with water as the only solvent in the presence of β-cyclodextrin (abbreviated as β-CD). Different factors influencing cinnamaldehyde oxidation

e.g

. reaction temperature

the amount of catalyst and oxidant

have been investigated. The yield of benzaldehyde reaches 76% under the optimum conditions (333 K

4 h

molar ratio of cinnamaldehyde to β-CD is 1:1). Furthermore

a feasible reaction mechanism including the formation of benzaldehyde and the two main byproducts (phenylacetaldehyde and epoxide of cinnamaldehyde) has been proposed.
