Synthesis and Structures of Novel Chiral Cyclic Hypervalent Iodine(III) Reagents for Metal‐Free Ligand‐Transfer Reactions

Chemistry – A European Journal, EarlyView.
Several new chiral cyclic hypervalent iodine(III) reagents have been synthesized and characterized. Carbon‐based ligands were successfully installed onto the hypervalent iodine centers, giving thus access to novel chiral cyano‐, trifluoromethyl‐ or alkynyl‐bearing λ3‐iodanes.

Synthesis of Chiral‐at‐Sulfur(VI) Sulfonimidamide Brønsted Acids

Chemistry – A European Journal, EarlyView.
A simple, modular route to chiral‐at‐sulfur(VI) Brønsted acids is described, delivering S‐chiral sulfonimidamides, C2‐symmetric acids, and BINOL‐based hybrid systems through stereospecific reactions of sulfonimidoyl fluorides and chlorides. ABSTRACT Herein, we report an efficient and simple strategy to access diverse chiral‐at‐sulfur(VI) Brønsted acids.
