Comparative assessment of methods for the preparation and characterization of polymer supported sulfonyl chloride resin (PS-TsCl)

摘要

Polystyrene derived sulfonyl chloride resin (PS-TsCl) is a resin-bound (polymer supported) equivalent of tosyl chloride. Commercially available variants of this resin typically employ a porous 1% cross-linked polystyrene-vininylbenzene matrix containing sulfonyl-chloride functional groups with the bead sized between 75-150 microns (100-200 mesh) and display loading capacities between 1.0-2.0 mmol/g and up to 2.0-3.0 mmol/g for high loading ones.
