Journal ArticleDOI
Konstitution und Reaktivität der dimeren Perchlorbutenine
TL;DR: In this article, the structure and reactivity of perchlorobenzocyclobutene (C8Cl8) were investigated. But the results showed that α-Cl8 is very easily attacked by nucleophilic agents, thus forming aromatic products derived from 7.7-fragmentation.
Journal ArticleDOI
Cyclooctatetraen‐Dihydropentalen‐Umlagerung von Perchlor‐COT und einige Polyhalogenderivate des Bicyclo [3.3.0] octans
TL;DR: Perchlor-COT1 lagert sich bei 180°C in die Dihydropentalene 2 and 4 um as mentioned in this paper, wahrend die dechlorierung von 4 das Tetrahydropents 7a ergibt.
Journal ArticleDOI
Dimere polyhalogenierter Benzocyclobutadiene
TL;DR: In this article, the perchlorinated derivative 6a splitts off chlorine at 400°C to form a dibenzopentalene, which is then isomerized to dibenzo[a,e]cyclooctenes 6 and 13.
Journal ArticleDOI
Plyhalogenierte Bicyclo[4.2.0]octa‐1,5,7‐triene, V. Aromatisierende nucleophile Substitutionen mit aliphatischen Aminen und Ammoniak
TL;DR: The bicyclic perchloro compound 1 reacts with primary aliphatic amines to yield the diimines 3a-d. as discussed by the authors, which may be transformed as well as 3a−d into 18c by bases.
