An easily available heterogeneous semiconductor material, g-CN, proved to be feasible when combined with homogeneous nickel catalysts for light-mediated C(sp2)-SO2Ar bond formation of aryl bromides with aryl sulfinates under mild conditions and base-free, unlocking a variety of cross-couplings. The metal-free heterogeneous semiconductor is totally recyclable from reaction system, and experimental results demonstrated a series of differently substituted substrates including electron donating groups and electron withdrawing groups can be tolerated with a satisfactory result. The method could even pro-duce the classic drug Dapsone in large scale, showing strong practical application potential.

The silicon-based cross-coupling reaction has attracted much attention over recent decades because there are many advantages in using organosilicon compounds. However, the use of reagents with a triorganosilyl group as a key function remains to be established. This account summarizes our recent progress in cross-coupling chemistry with such silyl reagents.1 Introduction2 Preparation of HOMSi Reagents from Aryl Bromides and Disilanes3 HOMSi Reagents from Heteroaromatics and Hydrosilanes4 Cross-Coupling Polymerization with HOMSi Reagents5 Cross-Coupling with Aryl(triethyl)silanes6 Amination of Aryl Halides with N-TMS-Amines7 Conclusion and Perspective

Photoredox/metal dual catalysis is a versatile tandem methodology to construct carbon–carbon and carbon–heteroatom bonds. The focus of this short review is the application of this technology to C(sp3)–C(sp3), C(sp3)–C(sp2), C(sp2)–C(sp2), C(sp2)–O, and C(sp3)–O bond formation induced by readily available and inexpensive carbonyl complexes as single electron transfer agents, photosensitizers, or hydrogen atom transfer agents.1 Introduction2 Homocoupling of Aryl Halides3 Functionalization of C(sp3)–H Bonds3.1 Dehydrogenation of Alkanes3.2 Arylation/Alkylation3.3 Carboxylation3.4 Acylation3.5 Hydroalkylation of Olefins3.6 Hydroalkylation of Imines4 Benzoylation of Aryl Bromides5 Aryl Esterification6 Oxidation of β-Keto Esters7 Conclusions and Future Outlook
