Re-Mediated C–C Coupling of Pyridines and Imidazoles

Abstract

Rhenium tricarbonyl complexes with three <i>N</i>-heterocyclic ligands (<i>N</i>-alkylimidazoles or pyridines) undergo deprotonation with KN­(SiMe₃)₂ and then oxidation with AgOTf to afford complexes with pyridylimidazole or bipyridine bidentate ligands resulting from deprotonation, C–C coupling and rearomatization
