Alkynyl‐Functionalized Imidazolium for “Click” Dendrimer Functionalisation and Palladium Nanoparticle Stabilization

Abstract

Abstract Functionalization of imidazolium salts (IMSs) that allow easy derivation of molecular or solid supports are called for in various applications. Here, the synthesis of an alkyne‐containing IMS can be achieved in three steps from 2,4,6‐trimethylaniline, and this IMS can be further successfully functionalized by using either Sonogashira or a “click” CuAAC reaction that was applied to dendritic IMS synthesis giving high yields. Applications are illustrated for Pd nanoparticle stabilization by the IMS dendrimer for Suzuki–Miyaura catalysis.
