Often stoichiometric amounts of gold find use in materials science; occasionally gold is even
used as a support. This review discusses the contributions of gold catalysis, both …

With low melting point, extremely low vapor pressure and non-flammability, ionic liquids
have been attracting much attention from academic and industrial fields. Great efforts have …

Abstract Azulene 1, pentalene 2, and heptalene 3 are classical nonalternant hydrocarbons.
Their fascinating π-frameworks, consecutive arrangements of odd-membered carbocycles …

Although polycyclic conjugated hydrocarbons (PCHs) and their analogues have gained
great progress in the fields of organic photoelectronic materials, the in‐depth study on …

Since the first isolation of 1, 3, 5, 7-tetra-tert-butyl-s-indacene in 1986, core-expanded s-and
as-indacenes have attracted intensive interest. However, there is no reported synthesis of …

Conspectus The activation of molecular hydrogen by main-group element catalysts is an
extremely important approach to metal-free hydrogenations. These so-called frustrated …

Three series of stable, neutral, π-extended bispentalene derivatives, with two pentalenes
fused to a central benzene or naphthalene moiety, have been prepared through a modified …

The coexistence of a strong Lewis acid and a Lewis base in solution, the so called frustrated
Lewis pair, has led to the discovery of metal-free hydrogen activation. Since then, this …

The development of the chemistry of non‐alternant non‐benzenoid hydrocarbons is
reviewed in connection with the I nternational S ymposium on N ovel A romatic C ompounds …

Two BN units were embedded in dibenzo [a, e] pentalene with different orientation patterns,
which significantly modulated its antiaromaticity and optoelectronic properties. Importantly …
