1,2,3‐Triazoles, as one of the most significant nitrogen‐containing heterocycles due to their extensive use in biology, material science and organic synthesis, have aroused great interest. 1,2,3‐Triazoles are commonly synthesized by metal‐catalyzed azide–alkyne cycloaddition and organocatalytic azide–carbonyl cycloaddition, which indispensably employ the toxic and potentially explosive azides. The azide‐free synthetic approaches provide a powerful and straightforward alternative to the assembly of diverse 1,2,3‐triazoles without the use of azides. In this review, we summarize the recent development of the construction of 1,2,3‐triazoles under azide‐free conditions.
