Surface modified activated carbon with methanesulfonic acid (AC-MsOH) is found to catalyze
[3+2] cycloaddition reactions between alkyl/aryl azides and nitroolefins which yielded regioselective
1,5-disubstituted-1,2,3-triazolines in high yields under mild conditions.
Keywords: Activated Carbon, [3+2] Cyclo-addition, 1, 2, 3-triazolines, nitroolefins.
