Cover Picture: Isolatable Organophosphorus(III)–Tellurium Heterocycles (Chem. Eur. J. 3/2014)

Abstract

Phosphorus sulfides have been known for over 270 years and are familiar to us in strike‐anywhere matches, which contain P4S3. Many phosphorus–sulfur and phosphorus–selenium compounds have been discovered and characterized but, in contrast, phosphorus–tellurium compounds are quite rare, since it is difficult to stabilise the PTe and PTe bonds. In their Full paper on J. D. Woollins and co‐workers present the first crystal structures of organophosphorus(III)–tellurium heterocycles, which can be stabilized and structurally characterized by the appropriate choice of bulky substituents or the installation of a PV2N2 anchor.
