Abstract
Herein, we introduce the first magnetic CuO nanoparticles based on carbon nanotubes as a highly intriguing magnetic catalyst in Ullmann-type coupling of aryl halides with phenols. Two facile procedures were used for the preparation of this magnetically separable catalytic system. Having been treated with FeSO4 and then H2O2, nanotubes accommodated the resulting iron hydroxides on the walls. The resulting nanocomposite was then exposed to ...
