Synthesis of a 3D-Network Polymer Based on a Calix[4]resorcinarene Containing N3Anion: A Green and Reactive Solid Supported Reagent

In this work, a cationic polymer containing pendant pyrazine groups was synthesized via twopost-functionalization steps. Initially, the active homogeneous moiety was chemically immobilizedonto a polymeric support based on calix[4]resorcinarene by silylation of the hydroxylgroups to form a cationic polymer that contains pyrazine moieties [1,2]. The formation of thiscationic polymer was confirmed by CHN, SEM, TGA and DTG analysis. Subsequently, N3anion was incorporated into the polymer along the pyrazine pendant groups via a well-knownion exchange reaction. Elemental analysis data revealed that the cationic polymer was convenientlyloaded with the desired N3 anion, therefore, it provides a novel polymer supportedreagent for achieving synthetic goals.
