Covering: up to 2014 Xanthone dimers are a widespread, structurally-diverse family of
natural products frequently found in plants, fungi and lichens. They feature an intriguing …

Previous studies have reported the arylation of unactivated arenes with ArX, base (KO t Bu
or NaO t Bu), and an organic additive at high temperatures. Recently, we showed that this …

We report a conceptually different approach toward E-stilbene syntheses by photoinduced
direct C–H arylation of alkenes at rt without the addition of transition metals, with a broad …

Direct intermolecular C–H arylation employing aryl bromide as the arene source has been
developed. This process proceeds via a simple transition-metal-free pathway. With the aid of …

An efficient rhodium (III)‐catalyzed coupling reaction of N‐aryloxyacetamides with 6‐diazo‐2‐
cyclohexenones through a cascade redox‐neutral C–H functionalization and aromatization …

A simple and novel method for the synthesis of novel 1, 3-dioxepine-fused (tricyclic)
bispyrazoles is described. It involves a Cs2CO3-mediated O-alkylation of readily available …

In the presence of a catalyst system consisting of Pd (OAc) 2, PCy3, and Zn (OAc) 2, the
reaction of alkynyl aryl ethers with bicycloalkenes, α, ß‐unsaturated esters, or heteroarenes …

A new, selective way to form C− C bonds has been developed. In this report, we disclose the
homolytic aromatic substitution via C→ O transposition coupled with the elimination of …

We report here the facile substitution of aromatic iodides with non-activated fluoroarenes
through radical-promoted reaction conditions. Applying the recently-popularized BHAS …

Homolytic aromatic substitution (HAS) encompasses a wide range of synthetic
transformations based on inter‐and intramolecular additions of radicals to arenes. This …
