Organic semiconductors have received broad attention and research interest due to their
unique integration of semiconducting properties with structural tunability, intrinsic flexibiltiy …

Low-valent early transition metals are often intrinsically highly reactive as a result of their
strong propensity toward oxidation to more stable high-valent states. Harnessing these …

A divergent synthetic strategy allowed access to several members of a new class of
helicenes, the “expanded helicenes”, which are composed of alternating linearly and …

Tetraazacoronenes were synthesized from bay‐functionalized tetraazaperylenes by Zr‐
mediated cyclization and four‐fold Suzuki–Miyaura cross coupling. In the Zr‐mediated …

Acene imides are expected to possess smaller band gaps than homologous acenes while
maintaining good solubility and stability. However, the design and synthesis of large acene …

Recently reported reactions of group 4 metallocene bis (trimethylsilyl) acetylene complexes
from the last two years are summarized. This could be considered as a never-ending story. A …

We report the synthesis and reactivity of Zr complexes supported by a 9, 10-anthracenediyl-
linked bisphenoxide ligand, L. ZrIVLBn2 (1) undergoes facile photolytic reduction with …

Recent advances in the chemistry of electron-poor polycyclic aromatic molecules are
reviewed with a focus on new structural designs and emerging synthetic methods. We …

This Review summarizes reactions of Group 4 metallocene bis (trimethylsilyl) acetylene
complexes with nitriles and isonitriles. Selected examples of reactions of Group 4 …

The Simmons–Smith reaction offers a direct route for conversion of an alkene into a
cyclopropane with a zinc carbenoid as the active intermediate. Zinc carbenoids, however …
