## Abstract A series of 1โ€substituted 4,5โ€diformylโ€[1,2,3]triazole derivatives were prepared by 1,3โ€dipolar cycloโ€addition of aryl azides with acetylene dicarboxaldehyde monoโ€diethylacetal. The triazoles were readily converted into 1โ€substituted [1,2,3]triazolo[4,5โ€__d__]pyridazines in good yields.
