, p. 12321 - 12324 (2017)
Here we report a novel electron-donor-acceptor (EDA) complex-enabled three-component cyanofluorination of vinyl azides under metal-free conditions in a cis-specific manner. This reaction protocol is operationally simple without exclusion of either moisture or oxygen, allowing access to a wide range of highly-functionalized α-azido-β-fluoronitriles bearing quaternary carbons that are difficult to obtain by existing methods.

Reported herein an unprecedented 1,2-azide migratory hydroazidation and subsequent gem-difluorination of alkynes accessing β-difluorinated alkyl azides. Importantly, functional group controlled 1,2-azide or 1,2-aryl migration was observed in the case of a
Photoredox-catalysed redox-neutral trifluoromethylation of vinyl azides for the synthesis of α-trifluoromethylated ketones

A redox-neutral, mild, and simple protocol is developed for the synthesis of α-trifluoromethylated ketones from vinyl azides under transition-metal-free conditions. In the presence of organic photoredox catalyst N-methyl-9-mesityl acridinium and sodium trifluoromethanesulfinate, a broad range of substituted vinyl azides were found to react smoothly upon visible-light irradiation, readily furnishing the corresponding products in satisfied yields.
