Hydrogenation of quinoline

Quinoline is easily hydrogenated, and the pyridine ring is generally easier than the benzene ring. For example, the use of metal hydrides, hydrogenation catalysts and other methods can successfully reduce quinoline to 1,2-dihydro and 1,2,3,4-tetrahydroquinoline. If platinum is used as the catalyst for hydrogenation in concentrated sulfuric acid, 5,6,7,8-tetrahydroquinoline can be obtained for an extended reaction time, and decahydroquinoline can be obtained.
