Conversion of PATP to DMAB based on Ag⁺‐induced catalytic oxidation

Abstract

In this paper, the Ag + is first adopted to oxidize PATP to DMAB, and the intermediate elementary Ag of the reaction is used to enhance the Raman signal, which acts as a surface-enhanced Raman scattering substrate and overcomes the drawbacks of the traditional metal sol. The experimental repetition rate reached 100%; the Raman peak of the product dimercaptoazobenzene was clear and obvious. Compared with the traditional silver sol system, the intensity of the Raman peak is increased by 10 times. It is believed that the results will make a great contribution to the future research of the surface plasmonassisted coupling reaction.

“…4f). This phenomenon indicates that the substrate exhibits plasmonic catalytic effect and the substrate is rich in plasmonic "hot spots" [32][33][34].…”

Surface Plasmon-Induced Hot Electrons as the Racemate to Regulate Ionization

“…The second hydrogen ion undergoes the same process to become another hydrogen radical, and then, the two hydrogen radicals join to form hydrogen. 23,24 The same process will occur for other hydrogen ions that are released. In this system, electrons flow from metallic silver to the organic compounds, which breaks the equilibrium of the system and initiates ionization.…”

“…Here, a Lewis acid is generated with a Lewis base that oxidizes H 2 O to • OH, which will eventually be quenched by the sacrificial agent of ethanol. , The introduction of p MBA confirmed that the chemical reaction was driven by plasmons. , In this system, the presence of large amounts of Lewis base disrupts the ionization equilibrium to release hydrogen ions, which capture the Lewis base into a hydrogen radical. The second hydrogen ion undergoes the same process to become another hydrogen radical, and then, the two hydrogen radicals join to form hydrogen. , The same process will occur for other hydrogen ions that are released.…”
