Photoinduced Electron Transfer (PET) as Key to Accelerate the Cycloreversion Reaction of Arylquadricyclanes

Chemistry – A European Journal, EarlyView.
It is demonstrated that the photoinduced cycloreversion of a methoxynaphthylquadricyclane in the presence of suitable photocatalysts gives quantitatively the corresponding norbornadiene. As this photochromic norbornadiene‐quadricyclane cycle has favorable properties for light energy conversion, this method provides a useful tool for the targeted ...

Controlling Aggregation‐Induced Emission by Sterics in Nitrogen–Boron–Nitrogen (NBN)‐Doped Tetraphenylethylene‐Like Molecular Propellers

Chemistry – A European Journal, EarlyView.
Nitrogen–boron–nitrogen (NBN)‐substituted molecular propellers are presented as structural framework for aggregation induced emission (AIE) applications. Steric hindrance is revealed to steer maximum‐AIE behavior, leading to refined control over assembly‐induced luminescence.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

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

Chemistry – 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 ...

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

Chemistry – 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 ...
