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 N-allylic compounds such as triallylamine and N,N-diallylaniline in dioxane in the presence of a catalytic amount of ruthenium(III) chloride hydrate and bis(diphenylphosphino)methane and tin(II) chloride dihydrate to afford the corresponding quinolines in high yields. Several other phosphorus ligands are also effective, but bis(diphenylphosphino)methane is the ligand of choice.
