5-dicarbonitriles) containing thioether linkages are prepared via the condensation of bis(cyanoacetamides) with α-substituted cinnamonitriles in the presence of piperidine. The target compounds can also be obtained via a three-component reaction of bis(cyanoacetamides) with two equivalents of both aldehydes and malononitrile in ethanol containing piperidine as a base.
