Abstract
Anilines react with allylammonium chlorides in an aqueous medium (H2O-dioxa ne) in the presence of a catalytic amount of RuCl2(PPh3)(3) together with S nCl2. 2H(2)O to give the corresponding quinolines in moderate to good yield s. The existence of SnCl2. 2H(2)O is necessary for the effective formation of quinolines, and a reaction pathway involving amine exchange reaction bet ween anilines and allylammonium chlorides to form an imine is proposed for this catalytic process.
