Copper-Catalyzed Alkynylation of C(sp3)?H Bonds in N-Fluoro-sulfonamides

Herein, we developed a copper-catalyzed approach for the remote C(sp3)?H alkynylation of N-fluoro-sulfonamides. With Cu(OTf)2 as the catalyst, the carbon radical which generated from nitrogen radical-mediated 1,5-hydrogen atom transf

Copper-Catalyzed Trifluoromethylalkynylation of Isocyanides

The title reaction proceeds with acetylenic triflones and isocyanides under mild conditions using copper as a catalyst. This transformation provides an efficient access to (E)-N-alkyl trifluoromethyl alkynyl ketoimines, which are useful building blocks for the synthesis of CF3-containing N-heterocycles, propargylamines, etc.
