Substituted quinolines were synthesized by the reaction of aniline derivatives with aliphatic alcohols and CCl4 upon the action of the FeCl3·6H2O catalyst.
A variety of aminoarenes react with aliphaticaldehydes in the presence of a catalytic amount of a rhodium complex and an excess amount of the corresponding nitroarenes at 180 °C to give 2-alkyl- and 2,3-dialkyl-substituted quinolines in excellent yields. Among the rhodium complexes examined, [Rh(norbornadiene)Cl]2 exhibits the highest activity as a catalyst. Thus, 2-methyl-, 2-ethyl-3-methyl-, 2-propyl-3-ethyl-
在催化量的铑配合物和过量相应硝基芳烃的存在下,多种氨基芳烃在 180 °C 下与脂肪醛反应,以极好的收率得到 2-烷基和 2,3-二烷基取代的喹啉。在所检测的铑配合物中,[Rh(降冰片二烯)Cl]2 作为催化剂表现出最高的活性。因此,2-甲基-、2-乙基-3-甲基-、2-丙基-3-乙基-和2-丁基-3-丙基喹啉衍生物很容易从氨基芳烃和乙醛、丙醛、丁醛和戊醛中获得分别。

Nitroarenes react with trialkylamines in the presence of a catalytic amount of a ruthenium catalyst together with tin(II) chloride dihydrate at 180 °C in an aqueousmedium (toluene–H2O) to afford the corresponding quinolines in moderate to good yields. The catalytic pathway seems to be proceeded via a sequence involving initial reduction of nitroarenes to anilines, alkyl group transfer from alkylamines
