The reactions of dichlorocarbene with propene, cis-butene-2, and trans-butene-2 produce chemically activated 1,1-dichlorocyclopropanes. The thermal decomposition of CCl₃SiX₃(X = F, Cl) yields singlet CC1₂ and SiX₃Cl. The rate constants 〈k_ai〉 of isomerization and decomposition of the chemically activated compounds were evaluated. The energy content of the carbene depends on the CCl₂-source.

Abstract

Die Reaktionen von Dichlorcarben mit Propen, cis-Buten-2 und trans-Buten-2 ergeben chemisch aktivierte 1,1-Dichlorcyclopropane. Der thermische Zerfall von CCl₃SiX₃(X = F, Cl) führt zu Singulett-CCl₂ und SiX₃Cl. Die Geschwindigkeitskonstanten 〈k_ai〉 der Isomerisierung und des Zerfalls der chemisch aktivierten Verbindungen wurden bestimmt. Der Energieinhalt des Carbens ist von der CCl₂-Quelle abhängig.
