Electron‐Catalyzed Fluoroalkylation of Vinyl Azides
Chemistry – A European Journal, 2016AbstractThe transition‐metal free fluoroalkylation of vinyl azides is herein reported. This operationally simple reaction employs the Togni reagent as a CF3 source, Bu4NI as an initiator, and occurs under electron catalysis. A range of readily prepared starting materials are functionalized using this approach to produce both phenanthridines and ...

Visible light-assisted chemistry of vinyl azides and its applications in organic synthesis.
Organic and biomolecular chemistry, 2023Vinyl azides have emerged as highly versatile precursors in organic synthesis due to their rich reactivity driven by the excellent leaving-group ability of molecular nitrogen.

Reaction of vinyl azides with nitrosyl tetrafluoroborate yields 1,2,5-oxadiazoles and 1,2,4-oxadiazoles depending on the structure of the azide. Reaction of 1,2-dialkyl vinyl azides with nitryl tetrafluoroborate gives 2-oxo-1,2,5-oxadiazoles in high yields whereas 1-aryl-2-alkyl vinyl azides gave moderate yields of 3-aryl-1,2,5-oxadiazoles and 5-aryl ...
