Tris(indol‐3‐yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. One product, tris(4‐bromo‐1‐methylindol‐3‐yl)methane, underwent a palladium‐catalyzed cascade reaction for the formation of a novel polycyclic heteroaromatic compound, where the methine C(sp3) atom originating from CO2 was ...

Rh(II)-Catalysed N2-Selective Arylation of Benzotriazoles and Indazoles using Quinoid Carbenes via 1,5-H Shift [PDF]
A Rh(II)-catalyzed highly selective N2-arylation of benzotriazole is developed with wide scope and good functional group tolerance. The reaction is also extended on indazole and substituted 1,2,3-triazole scaffolds.

Photochemical and Thermal Activation of a Diarylbismuth Azide
We report the synthesis and characterization of a novel diarylbismuth azide and its divergent reactivity upon thermal or photochemical activation. These findings contribute expanding the reactivity landscape of heavy pnictogen compounds and sets the basis for further investigations. ABSTRACT Azides are widely employed in synthesis as convenient nitrene

Photoredox-catalyzed arylation of isonitriles by diaryliodonium salts towards benzamides
The arylation of isonitriles by diaryliodonium salts under photoredox conditions has been proposed for the first time. The suggested procedure allows preparing a broad range of benzamides using both symmetric and unsymmetric diaryliodonium salts under ...

A rapid and efficient protocol for the synthesis of 2‐benzylbenzaldehydes and anthracenes is reported, based on the infrared (IR) irradiation‐assisted Pd‐catalyzed C(sp3)─H arylation and the tandem C(sp3)─H arylation/electrophilic aromatic cyclization of ortho‐tolualdehydes with aryl iodides via a transient directing group (TGD) strategy.

we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the
