A new, convenient method for the syntheses of 2-arylbenzothiazoles is described in the presence of catalytic amounts of Cu(OAc)(2)/MCM-41 under ultrasonic irradiation. Short reaction times, easy and quick isolation of the products, reusability of the catalyst and excellent yields are
A highly efficient copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) of 6-substituted tetrazolo[1,5-a]pyridines was developed for the preparation of 1-(pyridin-2-yl)-1,2,3-triazoles by simply using copper(I) acetate as a catalyst. The in situ formed HOAc played important dual roles and an activation of 2-azidopyridine-copper(I) complex

This work emphasizes the important role of the synthetic parameters in the structure of the polymeric material obtained in the aniline polymerization. The polymers formed by the oxidative polymerization of aniline by copper(II) ions in acidic aqueous solution, acetonitrile/water medium
