Photolysis of 1-aryl-3,3-dialkyltriazenes was written by Lippert, Th.;Stebani, J.;Nuyken, O.;Stasko, A.;Wokaun, A.. And the article was included in Journal of Photochemistry and Photobiology, A: Chemistry in 1994.Reference of 4714-63-0 This article mentions the following:
The photolytic decomposition of substituted 1-phenyl-3,3-diethyl-triazenes has been studied using both pulsed XeCl* excimer excitation at 308 nm, and continuous-wave irradiation with a xenon lamp. Electron-withdrawing substituents in the para position at the Ph ring are found to decrease both the quantum yield of photolysis and the apparent first-order rate constant of decomposition The reaction proceeds according to an overall one-step pathway; anal. of the photolysis products by gas chromatog.-mass spectrometry is consistent with a radical decomposition mechanism. For the compound 1-(4-nitrophenyl)-3,3-diethyl-triazene, an autocatalytic acceleration of the photolysis was observed during the continuous-wave irradiation, using a xenon lamp source. This phenomenon is analyzed in terms of an involvement of the nitro group: photoreduction of the latter functionality involves the creation of solvent radicals in comparatively large concentrations, which are detected by in-situ ESR experiments These radicals may attack and decompose further mols. of the starting material. In the experiment, the researchers used many compounds, for example, 4-(Ethylamino)benzonitrile (cas: 4714-63-0Reference of 4714-63-0).
4-(Ethylamino)benzonitrile (cas: 4714-63-0) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. Asymmetric bioreduction of nitriles is an attractive route to produce optically active nitriles as current metal-catalyzed hydrogenations tend to have low reactivity.Reference of 4714-63-0
