Metallacyclopentadienes, which possess two M–C (sp2) bonds and feature the structure of
M (CR1CR2–CR3CR4), are an important class of five-membered metallacycles. They are …

We report the first synthesis and structural characterization of free, uncomplexed phosphet-2-
ones. These unsaturated four-membered phosphacycles were prepared by phosphinidene …

An overview of η5, η1-coordinated transition metal ansa complexes is given. These
compounds bear one or more coordinated cyclopentadienyl moieties connected with a η1 …

A highly stereo-and chemoselective intermolecular coupling of diverse heterocycles with
dialkynylphosphine oxides has been realized via cobalt/rhodium-catalyzed C–H bond …

Benzo [b] arsole derivatives, being arsenic analogues of indole, were synthesized by
utilizing a safely prepared arsenic precursor. The structural and photophysical properties of …

Diarylbenzo [b] arsoles were synthesized from zirconacycles and diiodophenylarsine. The
structural modification to the luminophore was attained through diarylacetylene precursors …

A transition metal free route to phosphetes featuring an exocyclic alkene unit is presented. In
this approach phosphanides are added to a variety of diynes generating phosphaallylic …

The discovery and molecular engineering of novel electroluminescent materials is still a
challenge in optoelectronics. In this work, the development of new π‐conjugated oligomers …

Abstract This Focus Review summarizes transformations of 1‐alkynylphosphines and their
derivatives directed toward the synthesis of new phosphines. Owing to the importance of …

Silacycles play a very important role in modern organic chemistry and materials science.
Construction of silacyclic skeletons via metal-mediated or catalyzed Si-C bond cleavage has …
