Acid-Base Driven Ligand Exchange with Palladium(II) "Click" Complexes

Two simple palladium(II) pyridine‐2,6‐dicarboxamide complexes coordinated to CuAAC derived “click” 1,2,3‐triazole ligands are described. Addition of a more basic 4‐dimethylaminopyridine (DMAP) ligand to these palladium(II) “click” complexes leads to complete displacement of the 1,2,3‐triazole ligand...

Description
Summary:Two simple palladium(II) pyridine‐2,6‐dicarboxamide complexes coordinated to CuAAC derived “click” 1,2,3‐triazole ligands are described. Addition of a more basic 4‐dimethylaminopyridine (DMAP) ligand to these palladium(II) “click” complexes leads to complete displacement of the 1,2,3‐triazole ligands by DMAP. The process can be completely reversed by treatment with acid. When it clicks: Simple palladium(II) pyridine‐2,6‐dicarboxamide complexes coordinated to CuAAC derived “click” 1,2,3‐triazole ligands are shown to undergo stimuli responsive ligand exchange reactions with 4‐dimethylaminopyridine.
