Abstract

Abstract: The isolation of rhenium(V) complexes with terminal phosphide and arsenide ligands was achieved upon decarbonylation of rhenium(III) pnictaethynolates. One‐electron oxidation of the pnictide complexes yielded Pn−Pn (Pn=P, As) coupling products, which were spectroscopically and crystallographically characterized. Computational bond analysis suggests that these complexes are best described as {Pn2 } 0 complexes that are stabilized by donor–acceptor interactions with the metal and a pyrazole ligand. Abstract : Radikale Kupplung : Die Verwendung eines hemilabilen Liganden ermöglichte die Synthese und Isolierung von terminalen Rheniumphosphid‐ und Rheniumarsenidkomplexen aus Pnictaethinolat‐Vorstufen. Die Ein‐Elektronen‐Oxidation der Pnictidkomplexe führte zu einer intermolekularen Pn‐Pn‐Kupplung, die seitlich gebundene P2 ‐ und As2 ‐Verbindungen ergab.
