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

The preparation of functionalized 3,5-disubstituted cyclopent-2-enones via a solid-phase sulfone linker strategy is described. Polystyrene/divinylbenzene sulfinate 1 underwent S-alkylation followed by alpha,alpha-dialkylation with cis-1,4-dichloro-2-butene to form polymer-bound 3-phenylsulfonylcyclopentenes 8. Subsequent epoxidation of the cyclopentene moiety in 8 was accomplished by
