As the “chemical chameleon”, sulfonyl-containing compounds and their variants have been
merged with various types of reactions for the efficient construction of diverse molecular …

This article reviews synthetic transformations involving cleavage of a carbon–carbon bond of
a four-membered ring, with a particular focus on the examples reported during the period …

In recent years, radical C–C bond cleavage reactions have been increasingly understood
and used to perform transformations that complement traditional ionic processes. However …

Just as “Deconstructivism” appeared as a novel movement in architecture in the 1980s,
deconstructive approaches have recently emerged as excellent strategies for scaffold …

Recent years have witnessed a renaissance of radical cross‐coupling of cycloketone
oximes which served as active cyanoalkyl radical via ring fragmentation in various …

An efficient synthesis of cyanoalkylated heteroarenes via iron-catalyzed direct C–H
cyanoalkylation of heteroarenes has been developed. Structurally diverse cyanoalkyl motifs …

A photoinduced, phosphoranyl radical-mediated protocol for the direct N–O cleavage of
strained cycloketone oximes via a polar/SET crossover process was developed for the first …

A visible light-induced and exogenous photosensitizer-free, copper-catalyzed radical
aminocarbonylation of cycloketone oxime esters with CO gas and amines is developed. The …

Fine-tuned organic photoredox catalysts are introduced for the metal-free alkynylation of
alkylnitrile radicals generated via oxidative ring opening of cyclic alkylketone oxime ethers …

A visible-light-promoted redox neutral γ, γ-difluoroallylation of cycloketone oxime ethers with
trifluoromethyl alkenes through C–C and C–F bond cleavage has been achieved, which …
