clear light yellow to yellow-brown liquid

The Uses of 3,5-Bis(trifluoromethyl)aniline

3,5-Bis(trifluoromethyl)aniline was found to be a highly efficient monodentate transient directing group (MonoTDG) for the palladium-catalyzed direct dehydrogenative cross-coupling of benzaldehydes with arenes.

Synthesis

The synthesis of 3,5-Bis(trifluoromethyl)aniline is as follows is as follows:Put 259g (1mol) 3,5-Bis(trifluoromethyl)nitrobenzeneand 500g ethyl acetate into a 1L autoclave, add 5g palladium-carbon as a catalyst, raise the temperature to 60℃, then pass the hydrogen pressure to 2MPa, keep the temperature and react for 20 hours, then cooling, filtration, concentration, and distillation to obtain 3,5-Bis(trifluoromethyl)aniline with a purity of 98.5% and a yield of 87%.
