An alpha-thio-alpha-aryl-substituted alkanonitrile of the general formula ##STR1## wherein Ar represents an aromatic group, R represents a hydrogen atom or an alkyl group, R.sup.1 represents an alkyl group or an aromatic group, and Y represents an oxygen atom or a carbonyl group. The above compound can be prepared by reacting an alpha-aryl-substituted-alpha-thio-acetonitrile of the general formula ##STR2## wherein Ar, Y and R.sup.1 are as defined above, with an alkylating agent in the presence of a strong base. This compound is useful as an intermediate for producing an alpha-aryl-substituted alkane-carboxylic acid of the general formula ##STR3## wherein Ar, Y and R.sup.1 are as defined above.
通用公式为##STR1##的α-硫代-α-芳基取代的烷腈中,Ar代表芳香族基团,R代表氢原子或烷基基团,R.sup.1代表烷基基团或芳基团,Y代表氧原子或羰基。上述化合物可通过在强碱存在下,将通用公式为##STR2##的α-芳基取代-α-硫代乙腈与烷基化试剂反应制备。该化合物可作为生产通用公式为##STR3##的α-芳基取代烷基羧酸的中间体。
