Abstract

Quinoline, 2-methylquinoline, and 8-methylquinoline were hydrogenated over Raney nickel (R-Ni) under 10 atm hydrogen pressure at about 200° C and over ruthenium on carbon (Ru/C) under 100 atm hydrogen pressure at 150° C. All the substrates were commonly hydrogenated into the initial products, 1, 2, 3, 4-tetrahydroquinolines. The initial products were competitively converted over R-Ni to the final products, decahydroquinolines, directly ...
