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 ...

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 ...

Photolysis of vinylazide 1, which has a built-in acetophenone triplet sensitizer, in argon-saturated toluene results in azirine 2, whereas irradiation in oxygen-saturated toluene yields cyanide derivatives 3 and 4. Laser flash photolysis of azide 1 in argon-saturated acetonitrile shows formation of vinylnitrene 1c, which has a λmax at ∼300 nm and a ...

Computational Study on the Vinyl Azide Decomposition
The Journal of Physical Chemistry A, 2014The decomposition mechanism of vinyl azide (CH2CHN3) has been studied by calculations of the electronic structure. In addition, a study based on the topology of the electron charge density distribution and its Laplacian function, within the Quantum Theory of Atoms in Molecules (QTAIM), has been carried out with the aim of comprehending the electron ...

Isomerisation of Vinyl Sulfones for the Stereoselective Synthesis of Vinyl Azides
European Journal of Organic Chemistry, 2020Reported is the construction, and facile base‐mediated conversation of ten differently substituted 3‐azido E‐vinyl sulfones (γ‐azido‐α,β‐unsaturated sulfones) into their isomeric vinyl azide counterparts. The requisite 3‐azido E‐vinyl sulfones were prepared from 3‐bromo E‐vinyl sulfones, which in turn were accessed from allyl sulfones via a bromination‐

Bacterial adhesion onto azidated poly(vinyl chloride) surfaces
Journal of Biomedical Materials Research, 2002AbstractA plasticized poly(vinyl chloride) surface was modified by azidation using sodium azide in the presence of a phase transfer catalyst in aqueous media. Subsequent to azidation, the surface was crosslinked using ultraviolet radiation. Contact angle measurements showed that the surface became hydrophilic on azidation whereas photoirradiation did ...

Indium(III) Catalyzed Reactions of Vinyl Azides and Indoles
Organic Letters, 2020Indium trichloride catalyzes the reaction of vinyl azides with unfunctionalized indoles to give vinyl indoles. This is the first example of displacement of the azide group by a carbon nucleophile while preserving the vinyl function. The protocol employs very mild reaction conditions and offers excellent yields of diverse 3-vinyl indoles. It is amenable
