Synthesis of quinolines via ruthenium-catalysed amine exchange reaction between anilines and trialkylamines

Cho, Chan Sik,Oh, Byoung Ho,Kim, Joon Seok,Kim, Tae-Jeong,Shim, Sang Chul

, p. 1885 - 1886 (2007/10/03)

Anilines react with an array of trialkylamines in the presence of a catalytic amount of RuCl3*nH2O and bis(diphenylphosphino)methane together with SnCl2*2H2O and hex-1-ene as hydrogen acceptor in dioxane at 180 deg C to afford the corresponding 2,3-disubstituted quinolines in moderate to good yields.
