						This procedure makes allylbenzenes good phenethylamine precursors - just reduce the substituted phenylacetaldoxime to the phenetylamine using any known method. The Oxidation of Allylbenzenes by the System RuCl3-NaIO4-PTC Yoshifumi Yuasa; Shiroshi Shibuya; Yoko Yuasa Synth. Commun. 33(22), 3947-3952 (2003) (../rhodium /allylbenzene2phenylacetaldehyde.html) DOI:10.1081/SCC-120026319 Abstract Methyleugenol 1a was oxidized to give 3,4-dimethoxyphenylacetaldehyde 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.
