Summary: A highly efficient strategy has been developed for the direct thiolation of phenols under transition metal-free and solvent-free conditions. The reactions are operationally simple and employ air as an ideal oxidant, providing mono- and dithiolation products in good to excellent yields under basic conditions. This method tolerates a broad range of aryl thiols and arenes, making it especially applicable for large-scale synthesis.

Summary: A concept for intermolecular C-N cross-coupling amination has been discovered using tetrazoles and aromatic and aliphatic azides with boronic acids under iron-catalyzed conditions. The reaction follows an unprecedented metalloradical activation mechanism, different from traditional metal-catalyzed C-N cross-coupling reactions. The wide scope of this reaction has been demonstrated by employing various tetrazoles, azides, and boronic acids. Moreover, the reaction has shown potential for applications in medicinal chemistry, drug discovery, and pharmaceutical industries, as demonstrated by late-stage aminations and synthesis of a drug candidate.

Summary: This article proposes a new method for the direct hydroxylarylation of unactivated benzylic carbons (sp3/sp2/sp) without the need for pre-functionalized benzylic alcohols, aromatic aldehydes, or ketones. It features direct functionalization of unactivated benzylic C(sp3)-H bonds and benzylic sp2/sp-carbons, mild conditions (open air, room temperature), an environmentally friendly procedure (without any external catalyst/mediator/additive), and direct access to sterically hindered alcohols from inexpensive and readily available alkyl/alkenyl/alkynylbenzenes. Mechanistic studies strongly support the proposed radical-radical cross-coupling between transient ketyl radicals and persistent radical anions. Gram-scale synthesis and diversification of drug derivatives demonstrate the practical potential of this protocol.

Summary: A nickel catalysis strategy was developed to utilize alkyl xanthate esters as sulfenylating agents for C-S bond cleavage and cross-coupling reactions. This strategy enables the synthesis of thioesters and thioethers from a variety of carbon electrophiles in a practical and modular fashion. The use of alkyl xanthate esters as redox-active handles allows for regio- and chemo-selective C-S bond activation and cross-coupling reactions.
