Ionen des Typs [R Γ X Γ R] + mit X = Halogen werden als Haloniumionen bezeichnet. Sie treten sowohl cyclisch als auch offenkettig auf, bilden eine bedeutende Klasse von Oniumionen [1, 2] und spielen eine wichtige Rolle in der prΓ€parativen Chemie, z. B. als Zwischenstufen bei Friedel-Crafts-Alkylie
## Abstract Based on the density functional theory (DFT), the lattice constants and atomic positions of BiOX (X = F, Cl, Br, I) species have been optimized, and the electronic and optical properties of the relaxed species have been calculated, with Bi 5d states considered or not. Relaxation general
The kinetics of the thermal bromination reaction ( 3 ) have been studied in the range of 26lo-391"C. The observed rate law is compatible with initiation by the step (6) for which we obtain Brz + CsFsI -BrI + C6FsBr Br + C6FJ -BrI + C6F5 log k6(cm3/mol. sec) = (13.41 f 0.26) -(11700 f 700)/6 where 8
