Prior methods for visible-light-driven C–H arylation of quinoxalin-2 (1 H)-ones relied on
external photocatalysts. Herein, we report a photocatalyst-free approach for this arylation. In …

Herein, we disclose an electrochemical approach for the C (sp2)–H chalcogenation of
pyrazolo [1, 5-a] pyrimidines. This technique offers an oxidant and catalyst-free protocol for …

Irradiation of mixtures of title diazonium salts and heteroarenes with green light (510 nm) in
the presence of eosin Y disodium salt (EY-Na 2) as a photocatalyst furnished the …

A visible‐light‐induced, external photocatalyst‐free, site‐selective C− H arylation of 4H‐
pyrido [1, 2‐a] pyrimidin‐4‐ones and various 2‐aryl heteroarenes has been developed to …

An electrooxidative C− H functionalization is a widely accepted route to obtain sulfur‐
containing arenes and heteroarenes. However, this process often involves using non …

An environmentally sustainable, versatile, and cost-effective approach for C–Se and C–X
(X= I, Br, and Cl) bond formation through C–H functionalization assisted by micellar catalysis …

Late-stage functionalization of pyrido [1, 2-a] pyrimidin-4-one at pyrimidine ring structure is
