Metal‐Free Electrophilic Borylative Cyclizations of Alkynes

The Chemical Record, EarlyView.
Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...

Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

The Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

On Phosphatitanacycles

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Titanocene phosphinidenes react with terminal alkynes in formal [2 + 2] cycloadditions to give unsaturated [C2PTi] metallcycles. Diphosphene complexes in combination with aryl‐substituted alkynes react similarly to provide metallacyclopentenes. Titanocene‐phosphinidene and diphosphanediide (or diphosphene) complexes Cp2Ti(PMe3)PMesTer and Cp2Ti(P2Ar2) (

Scaffold Dependent Coordination Modes of Chelating PEP‐Type Ligands in Iron(0) Carbonyl Complexes (E = O, S)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The reaction of iron pentacarbonyl with various chelating diphosphine ligands containing oxygen or sulfur atoms in their backbone yields complexes that exhibit noteworthy coordination behavior. Depending on the natural bite angle of the ligands and the coordination behavior of the heteroatom, preferences regarding the coordination geometry are verified
