Synthesis of Dithienylcycloalkene Molecular Switches Enabled by a Bench‐Stable Ti‐Complex

open access: yesChemistry – A European Journal, EarlyView.
Herein we report a set of cycloalkene‐bridged DTEs with ring sizes ranging from 4‐ to 7‐membered rings. The synthesis of these analogs was performed via a key McMurry coupling step, which was enabled by a practical, bench‐stable Ti(IV)‐complex. Remarkably, it is shown that the strained cyclobutene bridge outperforms other rings, even the most commonly ...

Arene Incorporation and Ring Expansion in the Thermal Decomposition of a Divanadium(III) Complex With Four Bridging Methyl Groups

open access: yesChemistry – A European Journal, EarlyView.
Thermolysis of [{VCp*(µ‐CH3)2}2] (Cp* = η5‐C5Me5) in hexane leads to a tetranuclear cube‐type methylidene complex [{VCp*(µ3‐CH2)}4], while in benzenic solvents C6H5R produces the formal insertion of a CH fragment into the six‐membered aromatic ring of a solvent molecule to give trovacene derivatives with η7‐cycloheptatrienyl ligands [VCp*(η7‐C7H6R ...

Synthesis and Isolation of Bismuth Scorpionate Complexes: Toward Bond Activation via Bismuth‐Ligand Cooperation

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Over the past twenty years, main group chemistry has significantly expanded its scope to include reactivities once considered the exclusive domain of transition metals. Among the emerging concepts, element‐ligand cooperation has proven to be a powerful strategy for enabling bond activation reactions but remains relatively unexplored for ...

Metal Nanoparticles on Halloysite Applied in Stereoselective Hydrogenation of Tetrasubstituted Alkenes

open access: yesChemistry – A European Journal, EarlyView.
Composite materials based on metal nanoparticles supported on a naturally occurring nanotubular clay, halloysite (HAL), led to the diastereoselective hydrogenation of tetra‐substituted alkenes under relatively smooth conditions, mainly oxazolidinone‐based heterocycles.
