Cs. Cho et al., Synthesis of quinolines via ruthenium-catalysed amine exchange reaction between anilines and trialkylamines, CHEM COMMUN, (19), 2000, pp. 1885-1886
Anilines react with an array of trialkylamines in the presence of a catalyt
ic 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 g
ood yields.
