An alpha-thio-alpha-aryl-substituted alkanonitrile of the generalformula
wherein Ar represents an aromatic group, R represents a hydrogen atom or an alkyl group, R1 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 alapha-aryl-substituted -alpha-thio-acetonitrile of the general formula
wherein Ar, Y and R1 are as defined above, with an alkylating agent in the presence of a strong base. This compound is useful as an intermediate compound for producing an alpha-aryl-substituted alkane-carboxylic acid of the general formula
