| titleOfInvention | 4-halo-2-oxo-3-butenoic acid ester derivative and method for producing the same |
| abstract | (57) [Problem] The present invention is useful as an intermediate for the production of pharmaceuticals and agricultural chemicals, and as a raw material for producing fine chemicals. An object of the present invention is to provide a novel 4-halo-2-oxo-3-butenoic acid ester derivative and an efficient method for producing the same. The present invention provides an acetylene derivative in the presence of a transition metal complex catalyst. A method for producing a 4-halo-2-oxo-3-butenoic acid ester derivative, which comprises reacting a compound with an alkoxalyl halide, and the following general formula R 1 XC = CHCO obtained by the method. COOR 2 (wherein R 1 and R 2 represent an alkyl group, an aryl group, an aralkyl group, or the like which may have a substituent, and X represents a halogen atom). The present invention relates to a halo-2-oxo-3-butenoic acid ester derivative. |
