Abstract:
A cationic polymer containing pendant pyrazine groups was synthesized via postfunctionalizationof the polymeric backbone based on a calix [4]resorcinarene [1], and characterizedby AFM, TEM, analytical CHN, TGA, and DTG techniques. The functionalized polymeris conveniently loaded with desired anion thereby providing green and recyclable polymer-supported reagent for achieving synthetic goals. The thermal stability of this cationicpolymer (up to 250 °C by TGA) allows thermally demanding ring transformation and expansionof 2,4,6-triarylthiopyrylium salts [2] on its side chains and polymeric backbone withoutdecomposition and leaching of active species in the reaction media. The unique features ofthis polymeric reagent, such as superior thermal stability, recyclability, excellent activity interms of yield and reaction time are potentially important for the applications of this reagentin green synthesis of various compounds.
