Title
Polystyrene-supported ionic liquid copper complex: A reusable catalyst for one-pot three-component click reaction
Abstract

•A copper complex was attached to chloromethylated polystyrene.•A heterogeneous catalyst was prepared.•The catalyst was used for click reaction of alkynes and arylhalide.•The catalyst was reusable.

Copper(II) complex of 1,2-bis(4-pyridylthio)ethane immobilized on polystyrene was a used as a highly stable, active, reusable and green catalyst for click synthesis of 1,2,3-triazoles via one-pot three-component reaction of organic halides, sodium azide and alkynes. The catalyst was characterized by FT-IR spectroscopy, thermogravimetric analysis, elemental analysis, field emission scanning electron microscopy, energy dispersive X-ray, transmission electron microscopy and elemental analysis. High selectivity, broad diversity of organic halides or α-bromoketones and alkyl/aryl terminal alkynes, and excellent yields of the products were obtained using 0.2 mol% of catalyst. This catalytic system also showed excellent activity in the synthesis of bis-1,4-disubsitituted 1,2,3-triazoles. Moreover, the catalyst could be recycled and reused for seven cycles without any decrease in its catalytic activity.
