γ-3,4,5,6-Tetrachlorocyclohexene (γ-BTC) was synthesized in a yield of 14–30% by a Diels-Alder reaction between trans,trans-1,4-dichloro-1,3-butadiene and trans-dichloroethylene. The s-cis requirement and stereochemical relationships consistent with Alder’s rule are shown. Antioxidants are effective in this reaction.
Durch Diels‐Alder‐Reaktion des trans,trans‐Butadiens (I) mit dem Dichlor‐ äthylen (II) wird die Titelverbindung (III) dargestellt; das trans,cis‐Isomere (IV) von (I) gibt (III) in nur sehr geringer Ausbeute, und das cis,cis‐Isomere (V) reagiert überhaupt nicht.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
