The Knoevenagel condensation of phenylsulphonylacetonitrile and benzoylacetonitrile with 5-X-furane-2-carbaldehydes ( X = Br, NO2, C6H5S, C6H5SO2) has been used for preparation of the respective condensation products 1-cyano-1-fenylsulphonyl-2-(5-X-2-furyl)- and 1-cyano-1-benzoyl-2-(5-X-2-furyl)ethylenes. These condensation products react with nucleophilic reagents which replace the group X at the 5 position of the furane nucleus. These nucleophilic substitutions have been also studied kinetically.
