Title:
2-ベンゾイルオキシアセトアルデヒド誘導体の製造法
Document Type and Number:
Japanese Patent JP4653966
Kind Code:
B2
Abstract:
A process produces a 2-benzoyloxyacetaldehyde derivative represented by following Formula (3): wherein R1 and R2 may be the same as or different from each other and are each a hydrocarbon group, wherein R1 and R2 may be combined to form a ring with the adjacent oxygen-carbon-oxygen bond, and wherein the benzene ring in the formula may be substituted, by allowing a halogenated acetaldehyde acetal derivative represented by following Formula (1): wherein R1 and R2 are as defined above; and X represents a halogen atom, to react with a benzoate represented by following Formula (2): wherein M represents an alkali metal atom and wherein the benzene ring in the formula may be substituted, in the presence of an alkali-metal halide.
