摘要： The invention relates to a method for producing 2-dihaloacyl-3-amino-acrylic acid esters of formula (I). Said method is characterised in that acid halides of formula (II) are reacted with dialkyl amino-acrylic acid esters of formula (III), in which R, R1, R2, X1, X2 and Hal are defined as cited in the description, in a water-immiscible organic solvent in the presence of a base. The invention also relates to the novel 2-dihaloacyl-3-amino-acrylic acid esters of formula (I), to their use for producing 3-dihalomethyl-pyrazoles, to a method for producing 3-dihalomethyl-pyrazoles, in addition to novel 3-dihalomethyl-pyrazoles.
