A simple and efficient synthesis of organosilicon compounds containing 1,2,3-triazole moieties catalyzed by ZSM-5 zeolite-supported Cu–Co bimetallic oxides

A new efficient procedure for preparation of 1,2,3-triazole derivatives by 1,3-dipolar cycloaddition of benzyl halides, sodium azide, and propargyl alcohol over Cu–Co/ZSM-5 bimetallic nanocatalyst in aqueous media under conventional heating and ultrasonic irradiation was developed. The maximum activity of the catalyst was reported under ultrasonic irradiation with a noticeable reduction in the reaction time. The generated products were utilized as substrates for the synthesis of a series of new 1,2,3-triazole derivatives containing organosilylvinyl substituent and bulky organosilicon groups using (RSiMe2)3CLi (R = Me, Ph).
