Abstract:  2-Cyano-3-(5-methylthio- and 5-methylsulfonyl-2-furyl)acrylonitriles and methyl 2-cyano-3-(5-methylthio- and 5-methylsulfonyl-2-furyl)acrylates were prepared as model substances to study kinetics of nucleophilic replacement with secondary cyclic amines. Effects on the reaction rate of three different nucleophiles and of the electron-withdrawing group CH=C(Y)CN at position 2 of the furan ring were investigated. The results obtained were compared with kinetic data of the S_N reaction of 5-(4-X-phenylsulfonyl- or -phenyl thio)-2-furfurylidenemalononitriles.
