The reactions of 2-α-bromostyrylchromones or 2-styrylchromones with sodium azide afforded 4(5)-aryl-5(4)-(2-chromonyl)-1,2,3-triazoles. In the case of 2-α-bromostyrylchromones, the unexpected 1-aryl-5-(2-chromonyl- methyl)tetrazoles have been obtained as minor products and the mechanism of its formation is discussed. The bromination/dehydrobromination reactions of 2-styrylchromones were also studied.
