    Abstract: Beta -Phenyl-acrylic acid nitriles of the general formula

    IN WHICH X stands for a substituent; n denotes the numbers 0 to 3; R1 stands for an optionally substituted phenyl or naphthyl group, for an aromatic-heterocyclic radical which is linked via a carbon atom to the Alpha -carbon atom of the Beta -phenylacrylonitrile radical, or for a carboxyl group; and R stands for an alkyl group, for a radical

    WHERE R2 and R3 denote an alkyl radical, for a radical -So3Z where Z denotes H or a metal atom, or for a radical -CH2OR4 where R4 denotes an alkyl, aralkyl or aryl radical, and a process for their production characterised by treating toluene derivatives of the formula

    WHEREIN X, n and R have the meanings given above in an aqueousalkaline medium at temperatures of about 50* to 120*C with an alkali metal polysulphide and subsequently without intermediate isolation with nitriles of the formula
