Palladium/norbornene cooperative catalysis has emerged as a distinct approach to
construct polyfunctionalized arenes from readily available starting materials. This Review …

Contorted carbon structures have drawn much attention in the past decade for their rich
three-dimensional geometries, enhanced solubility, and tunable electronic properties. We …

Polycyclic conjugated hydrocarbons containing antiaromatic four‐membered
cyclobutadienoids (CDB) are of great fundamental and technical interest. However, their …

There has been a growing emphasis on the synthesis of polycyclic conjugated compounds,
driven by their distinct structural characteristics that make them valuable candidates for use …

According to the currently accepted structure–property relationships, aceno-pentalenes with
an angular shape (fused to the 1, 2-bond of the acene) exhibit higher antiaromaticity than …

The geometry, aromaticity, and electronic properties of benzo [3, 4] cyclobutathiophenes
(BCTs) and their homologues have been examined theoretically using density functional …

A palladium-catalyzed cyclobutanation of aryl sulfonates with strained alkenes has been
developed. The methodology is featured to achieve the cleavage of both C–O and C–H …

The investigation of the biphenylene (BP)‐tetracyanoethylene (TCNE) π‐molecular complex
is reported. The first study on this complex appeared in 1961 and was considered as a …

The serendipitous isolation of very small amounts of two naphthocyclobutadiene (NCB)
derivatives has led to the computational re‐examination of the electrocyclization of Z, Z‐3, 5 …

This chapter discusses the synthetic works in the field of non-benzenoid PH-based
diradicaloids, including the five-membered ring-containing diradicaloids, seven-membered …
