An efficient copper-TBAF-catalyzed C-N bond formation of sulfoximines with aryltrialkoxysilanes in dichloromethane at room temperature, affording the desired N-aryl sulfoximines in good to excellent yields under an oxygen atm., is reported. E.g., in presence of CuI-TBAF, N-arylation of sulfoximine derivative (I) with PhSi(OMe)3 gave 80% II. This method complements the existing synthetic approaches due to some advantageous properties of aryltrialkoxysilanes such as availability, low toxicity, ease of handling, high stability, and environmental benignity under mild reaction conditions, thus opening a new approach to practical C-N bond formation.

Herein, an Ir(III)-catalyzed asym. C-H activation enabled by noncovalent interactions was described. A broad range of sulfur-stereogenic sulfoximines, e.g., I was prepared in high yields with excellent enantioselectivities via the asym. C-H activation/annulation of sulfoximines with diazo compounds Desymmetrization, kinetic resolution, and parallel kinetic resolution were compatible with this protocol. Detailed DFT calculations suggested that the N-H¡¤¡¤¡¤O hydrogen bonding interaction between sulfoximine and the chiral carboxylic acid ligand was crucial for the high enantiocontrol. Moreover, chiral iridacycle intermediates were isolated, characterized, and subjected to stoichiometric reactions. Computational and exptl. studies suggested that the C-H cleavage step was the rate- and enantio-determining step.
