The title of the article was 《Switchable ROS Species Regulation Facilitates the Selective Oxidation of Benzyl Alcohols Enabled by an Organic Photocatalyst》.Name: 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine The author mentioned the following in the article:
Benefiting from the regulation of ROS species through a simple and feasible strategy, an efficient and switchable photocatalytic protocol for the chemoselective synthesis of aldehydes and carboxylic acids via oxidation of primary alcs. under mild conditions was developed. Using the pyridinium derivative as a metal-free organic photocatalyst, a variety of benzyl alcs. can be converted into aldehydes or carboxylic acids under an air atm. at room temperature with high selectivity and yield via simple solvent regulation. A feasible tandem reaction combining the pyridinium-catalyzed alc.-to-aldehyde conversion and catalyst-free photoinduced oxidation of aromatic aldehydes provides a powerful and efficient approach for the one-pot oxidation of benzyl alcs. to carboxylic acids, while a small amount of water can effectively regulate the competition of electron transfer and energy transfer and inhibit the generation of carboxylic acids, facilitating highly efficient and selective oxidation of alcs. to aldehydes. In the experimental materials used by the author, we found 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3Name: 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine)
4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3) belongs to pyridine derivatives. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals. Name: 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine
