Light Mediated Sulfonylation/C–H Activation/Annulation of Benzimidazoles Derivatives Catalyzed by Diarylmethylium Tetrafluoroborate Salts: An Experimental and Computational Study

Advanced Synthesis &Catalysis, EarlyView.
Through the exploiting of visible‐light, a key photoactive complex, and an acid‐catalyzed proton‐coupled electron transfer, polycyclic sulfonylated benzimidazoles are obtained through a domino process including sulfonylation, C–H activation, and annulation. Diarylmethylium tetrafluoroborates are employed as inexpensive organocatalyst capable of forming

Ruthenium‐Catalyzed Azide‐Selenoalkyne Cycloadditions: A Combined Synthetic–Computational Study into Reaction Scope, Mechanism, and Origins of Regioselectivity

Advanced Synthesis &Catalysis, EarlyView.
A ruthenium‐catalyzed azide–alkyne cycloaddition (RuAAC) reaction is reported for the synthesis of selenium‐substituted triazole products. Reaction regioselectivity is dependent on the identity of the non‐selenium substituent of the alkyne, which challenges the perceived understanding of RuAAC regioselectivity.

One‐Pot Cascade Synthesis of Isoquinolinone‐Fused Quinoxalines Through Sequential Rh(III)/Pd(II) Catalysis

Advanced Synthesis &Catalysis, EarlyView.
A new one‐pot, dual catalytic strategy for the synthesis of polycyclic isoquinolinone‐fused quinoxalines from commercially available N‐(2‐acetamidophenyl)benzamides and 1,3‐diynes is reported. This transformation proceeds via Rh(III)/Pd(II)‐mediated sequential NH/CH activation/annulation. Detailed mechanistic studies elucidate the reaction pathway. A

Cooperative Photocatalysis of 9,10‐Phenanthrenequinone and Sn(OTf)2 for Direct Mannich Reaction of Ethers via Hydrogen Atom Transfer Pathway

Advanced Synthesis &Catalysis, EarlyView.
A dual photocatalytic system of o‐PQ and Sn(OTf)2 enables visible light‐induced Mannich‐type addition of ethers to nitrones via Csp³–H activation. This oxidant‐free method offers broad scope and good yields. Mechanistic studies suggest that a photoexcited o‐PQ–Sn(II) complex mediates hydrogen atom transfer to form α‐oxy radicals for nitrone addition. A
