Abstract

An efficient copper-TBAF-catalyzed arylation of sulfoximines with arylsiloxanes in dichloromethane at room temperature affords the desired N-aryl sulfoximines in good to excellent yields under an oxygen atmosphere. This mild C-N bond formation complements the existing approaches due to the advantageous properties of arylsiloxanes such as availability, low toxicity, ease of handling, high stability, and environmental benignity.
