This review surveys recent progress in the chemistry of polycyclic heteroaromatic molecules
with a focus on structural diversity and synthetic methodology. The article covers literature …

The term “C–H functionalisation” incorporates C–H activation followed by its transformation.
In a single line, this can be defined as the conversion of carbon–hydrogen bonds into …

The activation of typically unreactive aromatic C–H bonds by transition-metal catalysis has
been receiving increased attention from the synthetic chemistry community in recent years …

Sulfonium salts are playing an increasingly significant role in contemporary organic
synthesis. In particular, the generation of radicals from sulfonium salts is a fundamental …

The intermediate oxidation state of sulfoxides is central to the plethora of their applications in
chemistry and medicine, yet it presents challenges for an efficient synthetic access, limiting …

Trifluoromethyl sulfoxides are a new class of trifluoromethylthiolating reagent. The sulfoxides
engage in metal‐free C− H trifluoromethylthiolation with a range of (hetero) arenes. The …

Nitrogen‐containing polycyclic aromatic compounds (N‐PACs) are an important class of
compounds in materials science. Reported here is a new aza‐annulative π‐extension (aza …

Thiophene‐based rings are one of the most widely used building blocks for the synthesis of
sulfur‐containing molecules. Inspired by the redox diversity of these features in nature, we …

An aryne reaction with alkynyl sulfides affording benzo [b] thiophenes is disclosed. A wide
range of 3-substituted benzothiophenes were synthesized from easily available o-silylaryl …

The application of alkylsulfonium salts as alkyl-transfer reagents in organic synthesis has
reemerged over the past few years. Numerous heteroatom-and carbon-centered …
