Descrizione generale

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.

Applicazioni

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

Several important chemicals, including formaldehyde, 1,4-dichloro-2-butene, bis-chloromethyl ether, hexamethylphosphoramide, and epichlorohydrin have been shown to produce nasal tumours in rats following repeated or continuous inhalation exposures. Some of these compounds are respiratory irritants. To determine whether there is a correlation
