Abstract
Scavengers are usually functionalized insoluble resins which react selectively with excess reagents or side products in a crude reaction mixture, leaving the desired product of enhanced purity remaining in solution. Since the pioneering work of Kaldor and co-workers 4 with polystyrene isocyanate resin (used to scavenge excess amine reactants in the formation of amides), a variety of new polystyrene-supported electrophiles including acid chlorides, 4 isothiocyanates, 5 and ...
