Abstract: The invention comprises compounds of the general formula in which R1 and R2 are each hydrogen or a C1-C4 alkyl group, n is 1 or 2, when n is 1 X is a cyano, nitrophenyl, chlorophenyl, phenylmercapto, alkylsulphoxy, phenylsulphoxy, alkylsulphone, phenylsulphone, nitrophenylsulphone, carboxylic acid alkyl ester, phosphonic acid dialkyl ester, diphenylphosphine or an acyl group and when n is 2 X is a 1,4-phenylene, thio, sulphoxy or a sulphonyl group. They are prepared by reacting a compound with at least an equivalent molar amount of a base. Specified bases are sodium and barium hydroxides, sodium methylate, potassium tertiary butylate, sodamide and lithium hydride. The reaction preferably takes place at 20 DEG to 120 DEG C. in presence of an inert gas, e.g. nitrogen, and a solvent, e.g. water, alcohols N-methylpyrrolidone, dimethylformamide, dimethylsulphoxide and tetramethyl sulphone.
