photoactive, ruthenium-based complexes bearing pyridine-quinoline or terpyridine ligands with extended aromatic conjugation. Our complexes were utilized in the atom transfer radical addition (ATRA) of haloalkanes to olefins, using bromoacetonitrile or bromotrichloromethane as the source of the alkyl group. The tailor-made ruthenium-based catalyst bearing the pyridine-quinoline bidentate ligand proved

In this article, we focus on the evaluation of tris[2-(dimethylamino)ethyl]amine (Me6TREN) ligand in copper catalyzed ATRA in the presence of free-radical diazo initiator AIBN (2,2′-azobis(2-methylpropionitrile)). The addition of carbon tetrachloride to 1-hexene, 1-octene and cis-cyclooctene proceeded efficiently to yield 89, 85 and 85% of monoadduct, respectively, using the catalyst to alkene ratio

Phenylglyoxylic acid can be employed in a very low catalyst loading (1 mol%) for the introduction of a low‐cost, simple, photochemical protocol for the ATRA reaction of BrCCl3 with olefins.
