The formation reaction of carbon carbon bond promoted by Eosin Y under visible light

Abstract

In recent years, photochemical organic conversion promoted by visible light has attracted the interest of many organic chemists. Compared with the traditional methods, visible light as the photoredox catalysis of renewable energy has been proved to be a mild and powerful tool that can promote the activation of organic molecules through the single electron transfer (SET) process. Therefore, the formation reaction of C-C bond can be achieved by activating these molecules with visible light, which can effectively modify the structure of these compounds and obtain compounds with multiple structures and functions. At present, this research has become an important research field in organic synthesis. Eosin Y, a cheap and widely-used organic dye, has been employed as an economically and environmentally friendly substitute for many transition-metal-based photo catalysts. In recent years, it has got much more attention due to its easy handling, eco-friendly and has great potential for applications in visible-light-mediated organic synthesis. This article reviews the research results on the formation of carbon carbon bonds promoted by organic photo catalyst eosin Y under visible light in recent years, and discusses representative examples and their different mechanistic pathways (such as SET, HAT, and Energy transfer).
