Our approach utilizes electrophilic azide groups, which promote fluoride elimination and enable nucleophilic addition to newly formed electrophilic sites. This method achieves rapid, high\u2010yield transformations of (per)fluoroalkyl azides into novel sulfur\u2010containing azides, imines, and triazoles under mild conditions and using inexpensive reagents. The reaction proceeds without metal catalysts or external energy input and displays broad functional group tolerance, including toward thiol\u2010sensitive motifs.
