Triazaadamantyl N-heterocyclic carbenes (NHC-TA): water-soluble ligands and silver complexes

Abstract

We report high-yielding preparations of two water-soluble NHC preligands bearing triazaadamantyl (TA) neutral hydrophilic groups. The NHC-TA derivatives were utilized in the synthesis of [AgCl(NHC-TA)] complexes, whose characterization included ¹⁰⁹Ag resonance determination. The hydrolytic stability of the silver complexes was found to depend on the NHC-TA ligand.
