Abstract:Two chelating N‐heterocyclic carbene (NHC) palladium complexes 3a‐b containing N‐(3‐bromopropyl)‐N′‐thioether difunctionalized imidazol‐2‐ylidene were synthesized by direct metalation of the precursor imidazolium salts and characterized by NMR and HR‐MS. The molecular structure of 3a has been further characterized unambiguously by X‐ray single crystal analysis. The subsequent substitution reaction with amine‐functionalized magnetic nanoparticles (MNPs‐NH2) afforded two highly active, stable, and recyclable mag… Show more
