A theoretical study of the chloronium and bromonium cations of cyclopropene, cyclobutene, cyclopentene and cyclohexene, have been studied at the ab initio MP2 and density functional B3LYP levels of theory implementing 6-311ΓΎΓΎG(d,p) basis set. The potential energy surfaces of all molecules under inv

## Abstract Amino acid and peptide radical cations, M^**.**+^, are formed by oxidative dissociations of [Cu(auxiliary ligand)(M)]^**.**2+^ and [Metal^III^(salen)(M)]^+^ complexes. The most easily formed radicals contain either an aromatic or basic amino acid residue. Aromatic amino acids have low i
A series of aryl substituted Coates and 2-adamantyl cations were generated and their 'jC NMR spectra determined to be consistent with sigma-bridged structures for the former, and unbridged structures for the latter. Of all the cations mentioned in the literature, the Coates cation (1) and some deriv
