Highly efficient, ambient-temperature, copper-catalyzed Atom Transfer Radical Addition (ATRA) of polyhalogenated compounds to alkenes in the presence of free radical initiator 2,2' -azobis (4-methoxy-2,4-dimethyl valeronitrile)(V-70)as a reducing agent was reported. The discrepancies between the alkene conversion and percent yield were mostly due to competing free-radical polymerization. ATRA of polyhalogenated compounds to monomers that are highly active in free-radical polymerization was not successful at 60 ° C when AIBN was used as radical initiator. The V-70 was proved to be very effective reducing agent, enabling selective formation of the monoadduct with α -olefins and highly active monomers such as methyl acrylate, methyl methacrylate, and vinyl acetate. The methodology for catalyst regeneration in copper-mediated ATRA in the presence of V-70 as a reducing agent also worked very well in the addition of CCl4 and CBr4 to highly active vinyl acetate.

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 tetrac
