Beschreibung

Allgemeine Beschreibung

cis-1,4-Dichloro-2-butene on reaction with sodium amide yields trans-1-chloro-1,3-butadiene. Mechanism of condensation of sulfone-activated methylene compounds with cis-1,4-dichloro-2-butene to yield cyclopentene has been investigated.

Anwendung

cis-1,4-Dichloro-2-butene was used in the preparation of functionalized 3,5-disubstituted cyclopent-2-enones.
