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 …

A thorough investigation of the reactions of diynes, R (C⋮ C) 2R, and polyynes, R (C⋮ C) n
R, with titanocene and zirconocene was performed using the metallocene sources Cp2M …

In this account [3]-and [5] cumulene complexes of group 4 metallocenes that form five-
membered metallacycles are described. These complexes have a “triple bond” despite their …

A thiophenoradialene-embedded polycyclic heteroterphenoquinone (PHTPQ) derivative of
diindeno [1, 2-b: 2′, 1′-d] thiophene-2, 8-dione, with antiaromatic characteristics, was …

[5] Radialene is known as an unstable cyclic hydrocarbon with a cross‐conjugated system.
Incorporation of heteroatoms into [5] radialene skeleton is an effective strategy for …

Benzo-zirconacyclohexadiene-phospha or silacyclobutene fused ring systems are easily
prepared via a benzynezirconocene intermediate by means of thermolysis of Cp2ZrPh2 in …

The first well-defined zirconocene complexes processing vinyl-imine and keteniminate
species have been achieved from zirconacyclopentenes or zirconacyclopentadienes and 2 …

Rasant entwickelt hat sich in den letzten Jahren die Chemie von Komplexen mit Zr‐P‐
Bindungen und die Anwendung dieser Verbindungen in der Organophosphorchemie. Dies …

Stereodefined butadienyl phosphines and related derivatives were readily prepared in high
yields with perfect regioselectivity via the zirconocene-mediated pair-selective coupling of …

Abstract 1, 2, 3, 4‐Tetrasubstituted cyclopentadienes and indene derivatives with identical or
different substituents were obtained in good to excellent isolated yields through a …
