Reactivity of a Methylene‐Bridged 1,3‐Bis(germylene) in Dynamic Equilibrium with Its Dimer
Angewandte Chemie, EarlyView.We report the properties and reactivity of an unprecedented methylene‐bridged 1,3‐bis(germylene) derivative. In the solid state, the 1,3‐bis(germylene) derivative undergoes dimerization to afford a 1,2,4,5‐tetragermacyclohexa‐1,4‐diene (Ge4CHD) derivative.

Angewandte Chemie, EarlyView.Carbatranes and anionic pincer ligands were self‐assembled via one‐pot C─F or C─O bond cleavage and the formation of C─O, C─N, or C─C bonds, forming ligand architectures inaccessible by common synthetic methods. This approach allowed to build a customizable library of nickel catalysts for light‐induced C─H bond trifluoromethylation.

Stepwise Acetylene Insertion and Ammonia Activation at a Digallene and Diindene
Angewandte Chemie, EarlyView.The stepwise insertion of acetylene into the E═E bonds of digallenes and diindenes is reported. This leads to the selective formation of four‐ and six‐membered rings with 2π E2C2 and 4π E2C4 cores. The six‐membered cyclohexadiene analogues are Lewis‐acidic and can form stable, isolable adducts with ammonia, which—upon heating—undergo ammonolysis ...

A C‐to‐B Atom Swap on Coumarins and Dibenzolactones
Angewandte Chemie, EarlyView.Cyclic boronic hemiesters, boron isosteres of lactones, display unique and valuable chemical properties. Herein, we report a novel method for their synthesis via nickel‐catalyzed decarbonylative borylation, enabled by electron‐rich phosphine ligands to achieve a formal “C‐to‐B” atom swap.
