Abstract

A novel Ru(phen)3 Cl2 -catalyzed free-radical chlorotrifluoromethylation reaction of unactivated olefins was investigated. Substituted 8-aminoquinoline-derived inert enamides were reacted with the Togni regent to afford a broad range of Cl-containing trifluoromethyl derivatives in good yields. The reaction proceeded at 90 °C and experimental result shows that the chlorine source of the products originated from LiCl.
