Sulfones and alkylnitriles play a significant role in both organic and medicinal chemistry, as versatile synthetic building blocks and privileged pharmacophores in many natural products and bioactive compounds. Herein, a room‐temperature, copper‐catalyzed radical cross‐coupling of redox‐active cycloketone oxime esters and sulfinate salts is described for the first time. Key to the success of this process

cross-coupling of cyclobutanone oxime esters with sulfonyl hydrazides has been developed. The copper-based catalytic system proved crucial for cleavage of the C−C bond of cyclobutanone oximes and for selective C–S bond-formation involving persistent sulfonyl-metal radical intermediates. This protocol is distinguished by the low-cost catalytic system, which does not require ligand, base, or toxic cyanide
