Transition metal-free organic transformations using K2S2O8 is one of the most efficient
methods for the formation of carbon–carbon/carbon–heteroatom bond in organic synthesis …

The direct functionalization of quinones has always fascinated research communities due to
their biological and redox activities and subsequent application. Quinone motifs play a vital …

Under oxidative conditions, 1, 4-dihydropyridines (DHPs) undergo a homolytic cleavage,
forming exclusively a Csp3-centered radical that can engage in the C–H alkylation of …

Contrary to the accepted convention, this work shows that Minisci-type C–H alkylation does
not require any metal, photocatalyst, light, or prefunctionalization of the readily available and …

We report herein an effective method for the halogenation of imidazo-fused heterocycles
using readily available sodium salts (NaCl/NaBr/NaI) as halogen source and K2S2O8 (or) …

Stainless steel-initiated thiosulfonylations of unactivated alkenes under solvent-free conditions in
a mixer mill - Green Chemistry (RSC Publishing) DOI:10.1039/D2GC02519A Royal Society of …

Two facile and effective C-3 arylation protocols of quinoxalin-2 (1H)-ones with
arylhydrazines and aryl boronic acids respectively via free radical cross-coupling reactions …

A simple method has been developed for the synthesis of 3-aryl quinoxalin-2-one
derivatives through an oxidative cross-coupling of arylboronic acids with quinoxalin-2-ones …

A PANI (polyaniline)-g-C3N4-TiO2 composite was prepared and found to be efficient for
radical C–H arylation reactions. The arylation process involved coupling of in situ generated …

Developing methods for the direct functionalization of quinones for assembly of highly
functionalized quinones or bioactive natural products is an essential topic in the field of …
