Alcohol‐Directed Carboamination of Conjugated Enynes

Angewandte Chemie, EarlyView.
The first general three‐component intermolecular Pd‐catalyzed carboamination of conjugated enynes enables the coupling of anilines and aryl triflates to produce functionalized allenic amines, utilizing a native alcohol directing group to control regioselectivity.

Seitliche π‐Koordination einer C≡C‐Dreifachbindung an Technetium forciert durch den As,CC,As Alkin‐Pinzetten‐Liganden 1,2‐Bis(2‐(Diisopropylarsaneyl)‐4‐(Trifluormethyl)phenyl)Ethin

Angewandte Chemie, EarlyView.
Technetium‐Alkin‐Komplexe konnten jahrzehntelang nicht isoliert werden, obwohl es zahlreiche Berichte über benachbarte Elemente gab. Der einzige Hinweis auf ihre Existenz war die Isolierung von Vinylidencarbenen oder deren Folgeprodukten. Stabile, kristalline Tc(III)‐ und Tc(V)‐Alkin‐Komplexe (sowie deren Re‐Analoga) eines auf Tolan basierenden As,CC ...

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 ...

Site‐Selective B─H Activation via HAT Toward Xanthyl‐closo‐Carboranes as Bench‐Stable Precursors of Organosulfur Boron Clusters

Angewandte Chemie, EarlyView.
A light mediated direct regioselective B─H functionalization, via hydrogen atom transfer (HAT), is described. Unexplored xanthyl‐closo‐carboranes as novel bench‐stable and versatile platforms to access sulfur‐containing boron clusters are reported for the first time.

Self‐Limiting Polymerization‐Induced Crystallization‐Driven Self‐Assembly (SL‐PI‐CDSA) Enables Templated Synthesis of Chiral Plasmonic, Hybrid 2D Hexagonal Assemblies

Angewandte Chemie, EarlyView.
This work details the rapid generation (t ≤ 5 min) of size‐tunable, ultralow dispersity (Ð ≤ 1.01) 2D hexagonal nanosheets by self‐limiting polymerization‐induced crystallization‐driven self‐assembly (SL‐PI‐CDSA) of modular and templating poly(aryl isocyanide) block copolymers, with functions that permit post‐polymerization modifications. Specifically,
