| titleOfInvention | Process for producing m-substituted-α-hydroxymethylstyrene derivative and 3-chloro-α-bromostyrene |
| abstract | (57) [Summary] [Object] To provide a method for producing an m-substituted-α-hydroxymethylstyrene derivative useful as an intermediate for pharmaceuticals and agricultural chemicals in a high yield. [Structure] 3-chloro-α-bromostyrene, and the following general formula (2): A metal magnesium is reacted with an m-substituted-α-bromostyrene derivative represented by the following general formula (3): A Grignard reagent represented by the following formula is obtained, and then the Grignard reagent is reacted with formaldehyde or paraformaldehyde, the following general formula (4): (In the above formulas (2) to (4), R 1 represents a chlorine atom, a fluorine atom, a trifluoromethyl group, an alkyl group having 1 to 10 carbon atoms or an alkoxyl group having 1 to 10 carbon atoms). Process for producing m-substituted-α-hydroxymethylstyrene derivative. |
