A green approach for the synthesis of 2-amino azoles by the reaction of 2-chloro azoles with various types of amines using water as an environment friendly solvent at room temperature has been developed. The significant features of this methodology are short reaction time and easy product separation. This approach provides various biologically active compounds in good to excellent yields without adding...
A facile, efficient, and environmentally-friendly one pot protocol has been developed for the synthesis of 1,4-diaryl-1,2,3-triazoles from boronic acids, sodium azide, and acetylenes using copper sulfate immobilized on chitosan as a recyclable heterogeneous catalyst. This green synthetic three component protocol avoids handling of hazardous and toxic azides involving its in situ generation. The use...
