A process for producing an .alpha.-arylalkanoic acid ester represented by the general formula ##STR1## wherein Ar represents an aryl group which may optionally be substituted, and R.sup.1 and R.sup.2, independently from each other, represent a lower alkyl group, which comprises reacting a Grignard reagent prepared from an aryl halide of the general formula Ar--X.sup.1 (II) wherein Ar is as defined above and X.sup.1 represents a halogen atom, and magnesium, with an .alpha.-haloalkanoic acid ester of the general formula ##STR2## wherein R.sup.1 and R.sup.2 are as defined above, and X.sup.2 represents a halogen atom, said reaction of the Grignard reagent with the .alpha.-haloalkanoic acid ester of general formula (III) being carried out in the presence of a nickel compound.
一种用于生产α-芳基烷基酸酯的方法,该酯由通式##STR1##表示,其中Ar代表可能被取代的芳基,而R^1和R^2分别表示独立的低碳基团,所述方法包括将由通式Ar-X^1(II)表示的芳基卤代烃(其中Ar如上定义,X^1代表卤素原子)和镁制备的格氏试剂与通式##STR2##表示的α-卤代烷基酸酯(其中R^1和R^2如上定义,X^2代表卤素原子)反应,其中所述格氏试剂与通式(III)的α-卤代烷基酸酯的反应在镍化合物存在下进行。
