Abstract:
The title compound, [PdBr(C(3)H(5))(C(9)H(8)N(2))], was synthesized by the reaction of the allyl-palladium(II) bromide dimer and 1-phenyl-1H-imidazole. The Pd atom is coordinated by one allyl group [in η(3) mode, the central CH group of the allyl group is disordered over two sets of sites in a 0.668 (5):0.332 (5) ratio], one bromide anion and a 1-phenyl-1H-imidazole ligand. Intra-molecular face-to-face π-π stacking inter-actions occur between adjacent phenyl or imidazole groups, with centroid-centroid distances in the range 3.877 (1)-3.6596 (6) Å, forming a supra-molecular chain along [100].

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
