Metallocene-Appended Imidazoles Displaying Virtual Planar Chirality
(S)-1-(1-Alkylethyl)imidazoles 6a/b (alkyl = cyclohexyl, tert-butyl) containing a 2-(η5-cyclopentadienyl)(η4-tetraphenylcyclobutadiene)cobalt substituent are readily synthesized.

The charge percolation mechanism and simulation of Ziegler–Natta polymerizations Part III. Oxidation states of transition metals [PDF]
The oxidation state of the transition metal (Mt) active centre is the most disputable question in the polymerization of olefins by Ziegler–Natta (ZN) and metallocene complexes.

Aktivierung von Metallkomplexen durch Ultraschallwellen für eine gezielte Krebstherapie
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.

Carbon nanotubes by the metallocene route [PDF]
Pyrolysis of metallocenes such as ferrocene, cobaltocene and nickelocene, is shown to yield carbon nanotubes and metal-filled onion-like structures. Pyrolysis of benzene in the presence of a metallocene gives high yields of nanotubes, the wall thickness ...
