Graphical Abstract

Suits all sorts: An efficient copper-catalyzed carbenoid insertion of 2,2,2-trifluorodiazoethane and 1-aryl 2,2,2-trifluorodiazoethanes into Si−H, B−H, P−H, S−H, and N−H bonds produced CF3-containing products in high yields (see scheme). Catalytic asymmetric Si−H and B−H bond insertion reactions were also developed with chiral bisoxazoline ligands, such as (Ra,S,S)-L1.

Abstract

Copper-catalyzed Si−H, B−H, P−H, S−H, and N−H insertion reactions of 2,2,2-trifluoro-1-diazoethane and 1-aryl 2,2,2-trifluorodiazoethanes generated a large number of new fluorine-containing chemical entities for medicinal chemists. With selected Si−H and B−H insertion reactions, we demonstrate successful extension to asymmetric catalysis.
