A five-membered metallacycloallene complex, 1-zirconacyclopenta-2,3-diene, was prepared from low-valent zirconocene and 2,4-bis(trimethylsilyl)but-1-en-3-yne. The complex reacted with carbonyl compounds to afford alkynyl alcohols after hydrolysis ...
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 five-membered ring structure, showing that they are regarded as 1-metall...
The (iminium ion)ruthenium(II) complex mer(Cl, Cl,Cl)-[RuCl(3){eta(2)-NCHCH(2)py(C(2)H(4)py)C(2)H(5)}] was synthesized via a C-H activation of the bridging ethyl group of an ethylbis(2-pyridylethyl)amine ligand and characterized by X-ray structura...

The first highly selective 1:2 cross-trimerization between triisopropylsilytacetylene and 2 equiv of internal alkynes, leading to 1,3-diene-5-yne compounds, was achieved using the Ni(cod)(2)/P(n)Pr(3) catalyst. Various symmetrical and asymmetrical...
