Bromination Of 1-Cyclopent-1-En-1-Ylbenzene And 1-(5-Bromocyclopent-1-En-1-Yl)Benzene And Theoretical Investigation Of The Products, Mustafa Ceylan, Armağan Kinal, Yaşar Sütbeyaz, Meti̇n Balci
Turkish Journal of Chemistry
The bromination of 1-cyclopent-1-en-1-ylbenzene (4) in different solvents and at different temperatures was accompanied by the evolution of hydrogen bromide and yielded 1-(5-bromocyclopent-1-en-1-yl)benzene (8). Further bromination of 8 gave exclusively 2R(S),5R(S)-1-(1,2,5-tribromocyclopentyl)benzene (11). The experimental results were compared with the theoretical ones based on semi-empirical (MM+ and AM1), Hartree-Fock (HF) and density functional theory (DFT). The formation of 11 was explained by the formation of a weakly bridged bromoniun ion of type 9.

Bromination Of Tricyclo[7.2.1.0^{2,7}]Dodeca-2,4,6,10-Tetraene Derivatives: Highly Brominated Benzobicyclic Systems, Ari̇f Daştan
Turkish Journal of Chemistry
The bromination reaction of tricyclo[7.2.1.0^{2,7}]dodeca- 2,4,6,10-tetraene derivatives was studied and the possible role of a substituent in rearrangements is discussed.
