Inter- versus Intramolecular Friedel-Crafts Reaction of Phenyl-substituted Dichlorocyclopropanes

Anke, Lutz,Weyerstahl, Peter

, p. 613 - 619 (2007/10/02)

Friedel-Crafts reactions of the phenyl-substituted dichlorocyclopropanes 1-9 show different results.Thus, 1 (-> 10, 11), 3 (-> 12), 4(-> 13), 6 (-> 14), 8 (-> 15), and 9 (-> 16) yield indenes by the known intermolecular reaction with benzene.However, 2 (-
