Electrochemistry Enabled Nickel-Catalyzed Selective C?S Bond Coupling Reaction

This work describes an electrochemical enabled nickel-catalyzed chemoselective C?S bond coupling protocol for the production of aryl sulfides and sulfones. By simply switching the nickel catalysts and electrodes, this electrochemical C?S bond coupling has demonstrated excellent redox activity, scalability and sustainability. Furthermore, the mechanism for this electrochemical cross-coupling reaction has been investigated.

Hantzsch Ester as a Visible-Light Photoredox Catalyst for Transition-Metal-Free Coupling of Arylhalides and Arylsulfinates

Diethyl 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (HEH) has been utilized as a visible-light photoredox catalyst for the cross coupling of arylhalides and arylsulfinates without transition metal, sacrificial agent, and mediator. This method is compatible with various functional groups and provides diaryl sulfones in good to high yields. Mechanistic studies indicate that this reaction undergoes the stepwise light irradiation of HE?, single electron transfer (SET) in donor–acceptor complex (DAC) from *HE? to arylhalide, trapping of aryl radical with sulfinate, and SET oxidation of sulfone radical anion by HE. to sulfone by the DAC method.

Selective Functionalization of Aminoheterocycles by a Pyrylium Salt

The functionalization of aminoheterocycles by using a pyrylium tetrafluoroborate reagent (Pyry-BF4) is presented. This reagent efficiently condenses with a great variety of heterocyclic amines and primes the C?N bond for nucleophilic aromatic substitution. More than 60 examples for the formation of C?O, C?N, C?S, or C?SO2R bonds are disclosed herein. In contrast to C?N activation through diazotization and polyalkylation, this method is characterized by its mild conditions and impressive functional-group tolerance. In addition to small-molecule derivatization, Pyry-BF4 allows the introduction of functional groups in a late-stage fashion to furnish highly functionalized structures.
