Visible-light-promoted oxidative dehydrogenation of hydrazobenzenes and transfer hydrogenation of azobenzenes

Abstract

Visible-light-promoted oxidative dehydrogenation of hydrazobenzenes and transfer hydrogenation of azobenzenes are realized using Eosin Y as the photo-catalyst.

Cross‐Linked Surface Engineering to Improve Iron Porphyrin Catalytic Activity

“…Finally, the intermediate (iii) was oxidized by Fe(III) to obtain the product 2 (iv). [ 53–55 ] For effectively improving the catalytic performance, the catalytic active site can be provided in the form of QTD TCPP‐Fe/Fe ultra‐thin metallized film. As shown in Figure 3b, QTD TCPP‐Fe/Fe ultra‐thin metallized film formed by deposition of TCPP‐Fe chelated with Fe(III) was loaded on the surface of hollow nanocage skeleton.…”

Encapsulation of Porphyrin‐Fe/Cu Complexes into Coordination Space for Enhanced Selective Oxidative Dehydrogenation of Aromatic Hydrazides

“…Aromatic azobenzene, as one of the oldest organic compounds, is widely used in the field of chemical industries. [50][51][52][53] Mitsunobu and co-workers put forward that the combination of diethyl azodicarboxylates and triphenylphosphine causes condensation reactions between alcohols and acids to obtain the corresponding esters. [54,55] Previous studies have reported that aromatic azobenzene exhibited effective catalytic ability for Mitsunobu reactions, in which traditional iron(II)phthalocyanine [Fe(Pc)] can be used as an oxidative dehydrogenation catalyst.…”

New Role for Photoexcited Na2 Eosin Y via the Direct Hydrogen Atom Transfer Process in Photochemical Visible-Light-Induced Synthesis of 2-Amino-4H-Chromene Scaffolds Under Air Atmosphere

“…Eosin Y is a metal-free organic dye that has gained widespread use in recent years as a cost-effective and environment friendly alternative to transition-metal-based photocatalysts ( Zhu et al, 2018 ; Wang et al, 2019 ; Yan et al, 2019 ; Chen et al, 2020 ). Successfully oxidized/reduced target substrates by their incited mode in eosin Y-catalyzed photoredox reactions are typically dependent on whether the substrates’ prospective oxidability or reducibility falls within the scope of eosin Y ( Yan et al, 2019 ).…”
