Open-shell radicals are usually thermodynamically and kinetically unstable due to their
incompletely satisfied valency. However, the rapid development of radical chemistry in the …

Heteroatom-centered diradical (oid) s have been in the focus of molecular main group
chemistry for nearly 30 years. During this time, the diradical concept has evolved and the …

Incorporation of main group elements into the π-conjugated frameworks is a sophisticated
strategy to alter the fundamental nature of the parent conjugated π-systems, giving rise to …

Conspectus Since the pioneering work by Thiele and Chichibabin, who synthesized the first
diradicals bridged by phenylene and biphenylene groups in 1904 and 1907, respectively …

π‐Conjugated chiral nanorings with intriguing electronic structures and chiroptical
properties have attracted considerable interests in synthetic chemistry and materials …

The employment of nitrogen Lewis acids based on nitrenium cations has been increasingly
featured in the fields of main group chemistry and catalysis. A formally reduced form of …

Herein we report the synthesis and characterization of anionic boron-and carbon-based
Kekulé diradicaloids spanned by ap-phenylene bridge. In contrast to Thiele's hydrocarbon, a …

In this article, some quinoidal p-quinodimethanes compounds that convert partially or
completely to diradicals or biradicaloids are analyzed. The aromatic/quinoidal balance is …

Well-defined 9, 10-bis (di (p-tert-butylphenyl) amino) anthracene serves as a photocatalyst
for radical fluoroalkylation under visible light irradiation. The diarylamine (Donor) …

Spin–Spin interactions between unpaired electrons in organic radicals are of utter
importance from the viewpoint of molecular magnetism and the development of smart …
