Anilines react with allylammonium chlorides in an aqueous medium (H2O–dioxane) in the presence of a catalytic amount of RuCl2(PPh3)3 together with SnCl2·2H2O to give the corresponding quinolines in moderate to good yields. The existence of SnCl2·2H2O is necessary for the effective formation of quinolines, and a reaction pathway involving amineexchange reaction between anilines and allylammonium chlorides

Anilines react with triallylamine in dioxane at 180 °C in the presence of a catalytic amount of ruthenium chloride and triphenylphosphine together with tin(II) chloride dihydrate to afford the corresponding 2-ethyl-3-methylquinolines in good yields.
