Controllable access to trifluoromethyl-containing indoles and indolines: palladium-catalyzed regioselective functionalization of unactivated alkenes with trifluoroacetimidoyl chlorides
of diverse products from the same starting materials is always attractive in organic chemistry. Here, a palladium-catalyzed substrate-controlled regioselective functionalization of unactivated alkenes with trifluoroacetimidoyl chlorides has been developed, which provides a direct but controllable access to a variety of structurally diverse trifluoromethyl-containing indoles and indolines.

including textiles and fabrics, and can serve as ideal supports of heterogeneouspalladiumcatalysts. An efficient strategy for the preparation of 2-(trifluoromethyl)quinazolin-4(3H)-ones via a three-component carbonylative reaction of trifluoroacetimidoyl chlorides and amines using a heterogeneous activated carbon fiber-supported palladiumcatalyst has been developed. In contrast to the homogeneous catalytic
