Oxidation of diastereomeric mixtures of 1-aryl-1-hydroxyprop-2-yl phenyl selenides, prepared either by phenylselenylation of propiophenones followed by reduction or by treatment of benzaldehyde with α-(phenylseleno)ethyl anion, with an excess of meta-chloroperbenzoic acid in methanol at 25 deg C for 24 h or at reflux for 2 h affords methyl 2-arylpropanoates almost quantitatively.Similar treatment in tetrahydrofuran at 25 deg C for 24 h results in a direct formation of 2-arylpropanoic acids in high yields.

Oxidation with m-chloroperbenzoic acid of the ethylene acetals of aryl α-phenylseleno- or aryl α-phenyltelluro-ethyl ketones prepared by treating the corresponding α-bromo compounds with diphenyl diselenide-sodium or diphenyl ditelluride-sodium, respectively, affords hydroxyethyl 2-arylpropanoates in moderate to good yields via aryl group migration.
