Palladium-catalyzed chloroimination of imidoyl chlorides to a triple bond: An intramolecular reaction leading to 4-chloroquinolines

In this paper, a new type of effective chloroimination was reported. This reaction afforded 4-chloro-2-perfluoroalkyl quinolines from fluorinated imidoyl chlorides in high yields. This is the first achievement of oxidative addition-reductive elimination type C-Cl bond activation by chloropalladation.
