Herein, a new application of an ionicliquid containing copper (I), ([Cu(Im12)2]CuCl2), is introduced. This ionicliquid was used as an efficient catalyst for the click cyclization between organic azides and terminal alkynes in various solvents. Then, the mixture of [bmim]BF4/[Cu(Im12)2]CuCl2 was used as a green catalytic medium for the multicomponent click synthesis of 1,4-disubstituted-1H-1,2,3-triazoles
An ionic liquid containing copper(I) is introduced as a new, green, homogeneous, and reusablecatalyst for click synthesis of 1,4-disubstituted-1H-1,2,3-triazoles from α-azido ketones and terminal alkynes in various solvents, especially in [bmim]BF4. These cyclization reactions were efficiently performed in the presence of introduced ionic liquid catalyst with short reaction times and good yields. This
Copper iodide nanoparticles on poly(4-vinyl pyridine): A new and efficient catalyst for multicomponent click synthesis of 1,4-disubstituted-1,2,3-triazoles in water
Polymer supported nanoparticles of copper(I) iodide is reported as a new, efficient and recyclable catalyst for the regioselective multicomponent synthesis of 1,4-disubstituted-1H-12,3-triazoles from alpha-halo ketones, sodium azide and terminal alkynes in water. This catalyst can be recovered by simple filtration and recycled up to 8 consecutive runs without losing its efficiency. (C) 2012 Elsevier B.V. All rights reserved.
