Abstract With Ag/g‐C 3 N 4 semiconductor as the heterogeneous photocatalyst, visible light promoted synthesis of unsymmetric diaryl chalcogenides could be achieved under additive‐free and mild conditions. A series were generated in good to excellent yields with high functional group tolerance. The photocatalyst is easily recovered from reaction mixture reused at least 5 times, opening way for larger‐scale industrial applications this type photocatalytic bond‐forming reactions.

We report an electrophotocatalytic process that enables the thiocyanation and sulfonylation/cyclization of alkenes. It is applicable to a wide range unactivated alkenes, using inexpensive photocatalyst 2,4,6-triphenylpyrylium tetrafluoroborate (TPPT) produce diverse array heterocycles containing sulfonyl thiocyano groups with good functional group tolerance. The protocol operates under mild, chemical oxidant- transition-metal-free, broad scope substrates. Preliminary mechanistic studies suggest reaction involves combination electrolysis reductive quenching photocatalytic cycle TPPT.

Abstract A highly effective oxidation cross-coupling method involving para-cresol derivatives and malononitrile has been developed utilizing undivided electrolytic conditions. This electrochemical approach offers a robust route for synthesizing diverse featuring quaternary carbon centers incorporating para-phenol groups. Notably, the direct electrooxidation of C(sp3)–H bond in derivative plays crucial role this process under Various with different substituents are readily compatible transformation, affording coupling compounds up to 99% yield.
