Polymers as High-Loading Supports for Catalysts

Williams and coworkers used a [G4]-PAMAM dendrimer as a scavenger in the reactions of an arylpiperazine with slight excesses of three different electrophiles (an isocyanate, a sulfonyl chloride, and a benzyl halide) [62]. After TLC had indicated that all amine substrate had reacted the dendritic scavenger was added. Solvent removal, adding of chloroform, and filtration of the unsoluble dendrimer afforded the products in high yields (87-99%) and purities ( 95%, HPLC). [Pg.331]
