The Oxidation of 3-Aryl-1-propenes by Oxidative System of RuCl₃-NaIO₄-Phase Transfer Catalyst

Abstract

Methyleugenol 1a was oxidized to give 3,4-dimethoxyphenylacet-aldehyde by the oxidative system containing the RuCl₃-NaIO₄-phase transfer catalyst. The yield and spectroscopic properties were obtained from the stable acetaldoxim 3a. Furthermore, this oxidation system could be applied to other arylpropenes, thus, safrole, 4-methoxyallylbenzene, allylbenzene, and the corresponding arylacetaldehyde formed.
