    Description / Table of Contents: Reactions of 3,4,4-Trichloro-3-butennitrile with Thiolates and AminesThe reactions of the title compound 2 with thiolates and amines start with a prototropic rearrangement to 4, followed by nucleophilic substitutions of chlorine to give the Z compounds 5 and 8, respectively, which completely or partly rearrange to yield the more stable E isomers 6 and 9, respectively. In the case of pentachlorothiophenolate, however, the Z isomer 5b is stable, probably due to steric reasons.
    Notes: Die Reaktionen der Titelverbindung 2 mit Thiolaten und Aminen beginnen mit der prototropen Umlagerung zu 4. Durch nucleophile Substitution von Chlor entstehen daraus die Z-Verbindungen 5 bzw. 8, die sich im weiteren Verlauf vollständig oder teilweise in die stabilen E-Isomeren 6 bzw. 9 umlagern. Das mit Pentachlorthiophenolat erhaltene Z-Isomere 5b ist wahrscheinlich aus sterischen Gründen stabil.
