Patent ID: 7692033

Claim:
A process for producing a 2-benzoyloxyacetaldehyde compound represented by the following Formula (3): wherein R 1 and R 2 may be the same as or different from each other and are each an aliphatic hydrocarbon group having from 1 to 6 carbon atoms, an alicyclic hydrocarbon group having 3 to 8 carbon atoms, an aromatic hydrocarbon group having 6 to 14 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an alkynyl group having 2 to 6 carbon atoms, or an aralkyl group having, the aliphatic hydrocarbon group and aromatic hydrocarbon group being bound to each other to form the aralkyl group, and wherein R 1 and R 2 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, the process comprising the step of allowing a halogenated acetaldehyde acetal compound represented by the following Formula (1): wherein R 1 and R 2 are as defined above; and X represents a halogen atom, to react with a benzoate represented by the following Formula (2): wherein M represents an alkali metal atom and wherein the benzene ring in the formula may be substituted, in the presence throughout the whole reaction of an alkali-metal halide, wherein the amount of the alkali-metal halide is 1 percent by weight or more based on the amount of the compound of Formula (1).
