Anilines react with an array of trialkylamines in the presence of a catalytic amount of RuCl3. nH(2)O and bis(diphenylphosphino)methane together with SnCl2. 2H(2)O and hex-1-ene as hydrogen acceptor in dioxane at 180 degrees C to afford the corresponding 2,3-disubstituted quinolines in moderate to good yields.
