Preparing method of Copper Nanoparticle and preparing method of triazole compounds using said Copper Nanoparticle as a catalysts

摘要

to which the present invention is a stable water-soluble copper nanoparticle synthesis by using a double- hydrophilic block copolymers as template relates . Of nanoparticles prepared acetylene compound and azide compound is [3 + 2] is used in the ring by the addition reaction catalyst to provide the product in high yield with a high position selectivity (regioselectivity). Copper nanoparticles can be re- used is at least three times under the same conditions without loss of catalytic activity . These block copolymers may be used in nano- reactor to produce a water-soluble catalyst metal nanoparticles for a wide variety of organic conversion reactions . ;
