Catalytic Decarboxylative Carboamination of 2-(Trifluoromethyl)acrylic Acid Using Oxime Esters via Photo/Thermal Relay

α-Trifluoromethylamines are prevalent in medicinal chemistry, yet synthetic approaches from readily available feedstocks remain limited. Herein, we report a visible-light-induced decarboxylative carboamination of commercially available 2-(trifluoromethyl)acrylic acid with oxime esters, enabling access to α-trifluoromethylimines that can be readily diversified into various α-trifluoromethylamine derivatives. The reaction proceeds under mild conditions and tolerates alkyl-, aryl-, and alkenyl-substituted carboxylic acid oxime esters. Furthermore, mechanistic studies provide detailed insights into the underlying reaction pathway.
