Abstract
In the present study, at first a magnetic starch oxide support that functionalized with histidine methyl ester was prepared. Then, histidine segments were alkylated with ethyl bromide to form imidazolium salts on this magnetic biopolymer hybrid. The successful synthesis of the prepared nanocomposite was proved by various analysis contain EDX, FE-SEM, FT-IR, VSM, ICP and XRD. The catalytic amount of this nanocomposite was accelerated coupling reaction of aryl boronic acids, NaN3 and phenylacetylene for the synthesis of different 1,4-diaryl-1,2,3-triazoles with high yields at proper reaction times under mild reaction conditions.
