Regioselective N/C-Heterocyclization of Allenylindium Bromide Across Aryl Azides: One-Pot Synthesis of 5-Methyl-1,2,3-triazoles

An unprecedented, one-pot regioselective synthesis of 1,5-disubstituted 1,2,3-triazoles through N/C-heterocyclization of allenylindium bromide across aryl azides is described. The synthesis is carried out under mild conditions in aqueous medium and proceeds regioselectively in moderate to good...
