Investigation of phenyl azide photochemistry by conventional and time-resolved spectroscopy. Elucidation of intermediates and reaction mechanisms

Autor: Elisa Leyva, Matthew S. Platz, Edgar Moctezuma

Publikováno v: Journal of Photochemistry and Photobiology, Vol 11, Iss , Pp 100126- (2022)

Early studies of the photochemistry of parent phenyl azide concerned the products obtained under specific experimental conditions. Depending on the products, various mechanisms and intermediates were proposed. Later work involving conventional spectr

Computational Exploration of Ambiphilic Reactivity of Azides and Sustmann’s Paradigmatic Parabola

Autor: Pengchen Ma, Xue He, Kendall N. Houk, Fang Liu, Dennis Svatunek, Pan-Pan Chen

Publikováno v: The Journal of Organic Chemistry

We examine the theoretical underpinnings of the seminal discoveries by Reiner Sustmann about the ambiphilic nature of Huisgen's phenyl azide cycloadditions. Density functional calculations with ωB97X-D and B2PLYP-D3 reproduce the experimental data a

Publikováno v: Molecules, Vol 18, Iss 7, Pp 8393-8401 (2013)

Photoaffinity labeling is a reliable analytical method for biological functional analysis. Three major photophores—aryl azide, benzophenone and trifluoromethyldiazirine—are utilized in analysis. Photophore-bearing l-phenylalanine derivatives, whi

Photo-immobilization of pseudozwitterionic polymers with balanced electrical charge for developing anti-coagulation surfaces

Autor: Jiae Seo, Joonbum Lee, Ji Hun Seo, Yun Chan Kang, Jinsung Park, Seungjoo Yi

Publikováno v: Journal of Industrial and Engineering Chemistry. 91:263-272

This study aims to develop an economical coating agent that can easily impart excellent anti-coagulative property onto polymer surfaces. To this end, photo-reactable pseudozwitterionic polymer comprising cationic ammonium, anionic carboxylic acid, an

Isomer-Selective Threshold Photoelectron Spectra of Phenylnitrene and Its Thermal Rearrangement Products

Autor: Wolfram Sander, Enrique Mendez-Vega, Patrick Hemberger

Publikováno v: The Journal of Physical Chemistry A. 124:3836-3843

The photoionization of phenylnitrene was investigated by photoion mass-selected threshold photoelectron spectroscopy in the gas phase. Flash vacuum pyrolysis of phenyl azide at 480 °C produces the nitrene, which subsequently rearranges at higher tem

Unravelling the strain-promoted [3+2] cycloaddition reactions of phenyl azide with cycloalkynes from the molecular electron density theory perspective

Autor: Nivedita Acharjee, Luis R. Domingo

Publikováno v: New Journal of Chemistry. 44:13633-13643

The strain-promoted [3+2] cycloaddition (SP-32CA) reactions of phenyl azide with a series of five strained cycloalkynes C5–C9 have been studied within molecular electron density theory (MEDT) at the MPWB1K/6-311G(d,p) computational level. These zwi
