The author of 《A Redox Active Nickel Complex that Acts as an Electron Mediator in Photochemical Giese Reactions》 were van Leeuwen, Thomas; Buzzetti, Luca; Perego, Luca Alessandro; Melchiorre, Paolo. And the article was published in Angewandte Chemie, International Edition in 2019. COA of Formula: C9H10O2 The author mentioned the following in the article:
A simple protocol for the photochem. Giese addition of C(sp3)-centered radicals to a variety of electron-poor olefins was reported. The chem. does not require external photoredox catalysts. Instead, it harnesses the excited-state reactivity of 4-alkyl-1,4-dihydropyridines (4-alkyl-DHPs) to generate alkyl radicals. Crucial for reactivity was the use of a catalytic amount of Ni(bpy)32+ (bpy=2,2′-bipyridyl), which acts as an electron mediator to facilitate the redox processed involving fleeting and highly reactive intermediates. In the experimental materials used by the author, we found 2-(Benzyloxy)acetaldehyde(cas: 60656-87-3COA of Formula: C9H10O2)
2-(Benzyloxy)acetaldehyde(cas: 60656-87-3) is a non-natural aldehyde. It undergoes enantioselective Mukaiyama aldol reaction with silylketene acetal nucleophiles in the presence of C2-symmetric bis(oxazolinyl)pyridine Cu(II) complex (catalyst).COA of Formula: C9H10O2
