Metal-Free Photoinduced Denitrogenative Alkylation of Vinyl Azides with Alkyl Radicals toward Ketones

Organic Chemistry Frontiers
A simple and general approach for synthesis of ketones via metal-free denitrogenative alkylation of vinyl azides with redox-active esters or Katritzky salts under visible light irradiation is described herein.

Bacterial adhesion onto azidated poly(vinyl chloride) surfaces

Journal of Biomedical Materials Research, 2002
AbstractA 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 ...

Divergent Reactivity of Iminyl Radicals in Four Interrupted Pathways for the Synthesis of Cyclic/Acyclic Ketones and N-Heterocycles from Vinyl Azides and Phenylacetic Acids.

Journal of Organic Chemistry
Herein, we report the Ag-catalyzed substrate-controlled interrupted radical pathways of the iminyl radical. The benzylic groups played a crucial role in pathway selection involving a series of dimerization and hydrolysis, a 1,5-H shift followed by ...

Electrochemically Induced Synthesis of Sulfonylated N-Unsubstituted Enamines from Vinyl Azides and Sulfonyl Hydrazides.

Organic Letters, 2020
Sulfonylated N-unsubstituted enamines were synthesized through a chain of chemical and electrochemical transformations via sulfonylation of vinyl azides. The disclosing of the N-unsubstituted enamines synthesis was based on a unique property of the azido

Indium(III) Catalyzed Reactions of Vinyl Azides and Indoles

Organic Letters, 2020
Indium 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

The microwave spectrum of vinyl azide

Journal of Molecular Spectroscopy, 1977
Abstract Vinyl azide has been shown to exist in both cis and trans conformations with the cis more stable by 460 cal/mole. The rotational constants in Megahertz are: cis, A = 14 698.23, B = 4088.44, C = 3195.64; trans, A = 46 761.19, B = 2751.40, C = 2598.83.
