Barton esters were prepared starting from different carboxylic acids loaded on a Wang resin. Light induced fragmentation occurred giving a radical that reacted with CBrCl 3 to give the corresponding bromides, whereas conjugate addition to electron-poor alkenes proved to be less synthetically useful.
## 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
