Abstract
Reduction of (trifluoromethyl) quinolines by nucleophilic attack of hydride was studied. Sodium borohydride reduced only 3-(trifluoromethyl) quinoline to methyl derivative, while lithium aluminum hydride reduced other isomers to methylquinolines and 3-(trifluoromethyl) quinoline to 3-(difluoromethyl)-1, 2-dihydroquinoline. The mechanisms were proposed.
