Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis
Asian Journal of Organic Chemistry, EarlyView.This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

Near‐Zero Thermal Expansion in Coordination Polymer Cd(1,2,4‐Triazole)2(H2PO4)2
Angewandte Chemie, EarlyView.The structural dynamics and the chemical bonding origin of a volumetric near‐zero thermal expansion in a coordination polymer across 25 K to 400 K is studied using multi‐temperature X‐ray crystallography and X‐ray electron density analysis. The lattice expansion in the a and c directions is counteracted by contraction along b axis, caused by concerted ...

Crystallization of L‐Cysteine in Heavy Water Induces Intrinsic Fluorescence
Angewandte Chemie, EarlyView.Crystallization of L‐Cysteine in D2O${\rm D}_2{\rm O}$ generates a remarkably different structure compared to H2O${\rm H}_2{\rm O}$. The crystals formed in D2O${\rm D}_2{\rm O}$ display enhanced intrinsic fluorescence, and using state‐of‐the‐art excited state simulations, we determine the molecular origins of this luminescence and propose design ...

Angewandte Chemie, EarlyView.Bislang unbekannte Gruppe‐9‐Tetrylidine werden in einer One‐Pot‐Synthese dargestellt. In einer neuartigen Metathesereaktion reagieren die Plumbylidine mit Terphenylstannylenchlorid zu den entsprechenden Stannylidinkomplexen. Die Germylidine werden aus den jeweiligen Stannylidinverbindungen in der Umsetzung mit Terphenylgermylenchlorid erhalten ...

Access to N‐Monofluoromethylated (Thio)Carbamates, Formamides, Alkynamides, and Related Derivatives
Angewandte Chemie, EarlyView.The first general synthetic access to N‐CH₂F and N‐CHRF carbamates, thiocarbamates, formamides, alkynamides, and related compounds is disclosed. The method involves the direct synthesis of carbamoyl fluoride building blocks from readily available amines, followed by their derivatization. Abstract This work presents the first general synthetic access to
