Kinetic Study of the Radical Azidation with Sulfonyl Azides

Australian Journal of Chemistry, 2013
Rate constants for the reaction between a secondary alkyl radical and two different sulfonyl azides were determined using bimolecular competing radical reactions. The rates of azidation were determined by competition with hydrogen atom transfer from tris(trimethylsilyl)silane ((TMS)3SiH) of the 4-phenylcyclohexyl radical. 3-Pyridinesulfonyl azide and

Alkyne Phosphonites for Sequential Azide–Azide Couplings

Angewandte Chemie International Edition, 2013
Modern research often demands the modular conjugation of molecular systems with functional modules including fluorophores, purification tags, solubility enhancers, isotopic labels, or biologically active ligands, which enable their functional analysis, tracking in complex environments, and aids in several medicinal and pharmaceutical applications. Such

Dual Roles of Azide: Dearomative Dimerization of Furfuryl Azides

The Journal of Organic Chemistry, 2022
A dearomative dimerization of furfuryl azides for the construction of furfuryl triazoles is developed. As a rare leaving group, azide is capable of initiating the generation of a furfuryl cation under the Lewis acid-catalyzed conditions, followed by reacting with the other azide to realize an intermolecular [3 + 2] cycloaddition/furan ring-opening ...

Pyrolysis of aryl azides. II. Naphthyl azides

Australian Journal of Chemistry, 1972
Kinetic studies of the pyrolyses of 1- and 2-naphthyl azides reveal neighbouring group participation by nitro and phenylazo substituents. The acceleration observed in 1-nitro-2-naphthyl azide, 1-phenylazo-2-naphthyl azide, and 2-nitro-1-naphthyl azide is 1730-, 211-, and 23.6-fold, respectively, in nitrobenzene solution at 120 .

Thermochemistry of azides I. The standard enthalpy of formation of ammonium azide and of the azide ion

The Journal of Chemical Thermodynamics, 1990
Abstract The standard ( p ⊖ = 0.1 MPa ) molar enthalpy of formation of ammonium azide at 298.15 K has been derived from measurements of the energy of combustion in oxygen as Δ f H m ⊖ (cr) = (114.14±0.94) kJ·mol −1 . From measurements of the molar enthalpy of solution of NH 4 N 3 (cr) in water, the value
