First rhenium complexes based on cyclotriphosphazene scaffolds with exocyclic pyrazolyl substituents†
Abstract
Functionalized cyclotriphosphazenes with two or six pyrazolyl substituents have been employed for the preparation of rhenium carbonyl complexes; depending on the nature of the ligand system rhenium complexes with either gem-N2, gem-N3 or non-gem-N3 coordination modes can be prepared.
