Abstract
Herein, we disclose a novel and efficient cobalt-catalyzed cross-coupling strategy for picolinamide-directed direct C(sp(3))-H bond formation with N-(phenylsulfanyl)succinimides. This method enables the direct construction of C(sp(3))-S bonds under mild conditions and exhibits excellent functional group tolerance along with a broad substrate scope. Notably, the catalytic system achieves oxidative C-H functionalization without relying on costly or environmentally detrimental oxidants, offering a more sustainable and practical alternative for C-S bond formation.
