Angewandte Chemie, EarlyView.The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Intermolecular Electrophilic Germylation Using GeCl4 and Al2Cl6
Angewandte Chemie, EarlyView.While electrophilic aromatic substitution is well‐established for carbon and silicon‐based electrophiles, it is extremely underdeveloped for germanium. Herein we report the first effective intermolecular Germa–Friedel–Crafts reaction. The process can be modified to enable selective synthesis of the mono‐ or the di‐aryl germane derivatives, ArGeCl3 and ...

Homoleptic and Heteroleptic Borylones L1‐B(Ph)‐L2
Angewandte Chemie, EarlyView.Density functional theory and CCSD(T) calculations reveal that homoleptic and heteroleptic borylones L1–B(Ph)–L2 are thermodynamically accessible. Remarkably, the homoleptic borylones B(Ph)(N2)2 and B(Ph)(SPh2)2 exhibit higher bond dissociation energies than the related carbones.

One‐Pot Amidation/C─H Halogenation by an Efficient Electrochemical Cascade
Angewandte Chemie, EarlyView.A sustainable electrochemical cascade enables the one‐pot synthesis of regioselectively halogenated N‐aryl amides from readily available amines and acyl halides under mild conditions. The method merges amidation and C─H halogenation in a single operational step, delivering broad substrate scope, high selectivity, and scalability, and provides an ...
