Abstract

Mono(thio)substituted butadiene compounds 3a-c are prepared by mixing 2-nitropentachlo-robutadiene (1) with thiols (2a-c). 2-Nitrodiene 1 gives bis(thio)substituted 4a and 4d by the reaction with the same thiols in EtOH containing sodium hydroxide. N,S-Substituted 1,3-butadienes 6a-h were obtained by the reactions of 3a-c with primary amines. S-Substituted nitrodiene compounds 3a-c give 8a-c and 10a-c by the reaction with piperazines 7 and 9 in ether.

Die Mono(thio)substituierten Butadien-Verbindungen 3a-c werden durch Umsetzung von 2-Nitropentachlorobutadiene (1) mit Thiolen (2a-c) präpariert. Bei der Reaktion von 2-Nitrodiene 1 mit denselben Thiolen in EtOH entstehen bis(thio)-substituierte 4a und 4d. N,S-Substituierte 1,3-Butadienen 6a-h sind durch Umsetzung von 3a-c mit primären Aminen gewonnen worden. S-Substituierte Nitrodienverbindungen 3a-c geben bei der Reaktion mit den Piperazinen 7 und 9 in Ether 8a-c und 10a-c.
