    摘要: 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.
