Chiral sulfilimines, aza analogues of sulfoxides, are essential in natural products and pharmaceuticals, highlighting the importance their synthesis asymmetric catalysis. However, efficient approaches for synthesizing chiral diaryl sulfilimines still rare challenging, particularly those with two sterically similar aryl groups. Herein, we present a mild protocol generating diverse enantioenriched alkyl via copper-catalyzed enantioselective S-arylation N-acyl sulfenamides diaryliodonium salts. A bulky PyBox ligand is crucial stereocontrol, delivering various up to 95% ee (51 examples).

Abstract Utilization of clean and low‐cost water as the reductant to enable hydrogenation alkenes is highly attractive in green chemistry. However, this research subject considerably challenging due sluggish kinetics oxidation half‐reaction. It also very difficult avoid undesired because that far easier occur than desired from thermodynamic standpoint. Herein, challenge overcome by applying a cooperative catalysis where HCl used cocatalyst accelerate Pt/g‐C 3 N 4 ‐catalyzed suppress alkene. This provides an example for using proton source photocatalytic alkenes. The present method exhibits broad substrate applicability, allows various arylethenes aliphatic undergo smoothly.
