N‑Arylations of Sulfoximines with 2‑Arylpyridines by Copper-Mediated Dual N–H/C–H Activation

A high-yielding method providing rapid access to new N-arylated sulfoximines has been developed. A stoichiometric amount of copper facilitates the C–H activation of 2-arylpyridines which then undergo oxidative C–N cross-couplings with various sulfoximine derivatives.
