Redefining The Mechanistic Scenario Of Carbon-Sulfur Nucleophilic Coupling Via High-Valent Cp*Co-Iv Species

The potential access to Co-IV species for promoting transformations that are particularly challenging at Co-III still remains underexploited in the context of Cp*Co-catalyzed C-H functionalization reactions. Herein, we disclose a combined experimental and computational strategy for uncovering the participation of Cp*Co-IV species in a Cp*Co-mediated C-S bond-reductive elimination. These studies support the intermediacy of high-valent Cp*Co species in C-H functionalization reactions, under oxidative conditions, when involving nucleophilic coupling partners.
