    摘要： PURPOSE:To obtain an aldehyde in high yield, by reacting a compound easily obtained by condensing an alkali metallic salt of methoxyphenylthiomethane with an organic halide, etc. with an organic peracid under neutral conditions at a low temperature. CONSTITUTION:A compound of formula I (R is alkyl, alkenyl, aryl or aralkyl which may respectively have substituent groups; ph is phenyl) is reacted with an organic peracid, e.g. m-chloroperbenzoic acid, under refluxing conditions of a solvent to give the aimed aldehyde of formula II. The starting compound of formula I is obtained by reacting methoxyphenylthiomethane with an alkali metal, e.g. butyl lithium, to give an alkali metallic salt, and condensing the resultant alkali metallic salt with an organic halide or carbonyl compound. According to this method, the organic halide or carbonyl compound as a starting material provides the aimed aldehyde having one more carbon atom by the formation of the C-C bond.
