Visible light-mediated selective and efficient oxidation of various primary benzyl alcs. RCH2OH (R = Ph, 2-bromophenyl, pyridin-2-yl, etc.)/secondary benzyl alcs. such as 1-(phenyl)-ethanol, diphenylmethanol, 1-phenylethane-1,2-diol, etc. to aldehydes RCHO/ketones such as acetophenone, benzophenone, chalcone, etc. and oxidative dehydrogenation (ODH) of partially saturated heterocycles using a scalable and reusable heterogeneous photoredox catalyst in aqueous medium are described. A systematic study led to a selective synthesis of aldehydes under an argon atm. while the ODH of partially saturated heterocycles under an oxygen atm. resulted in very good to excellent yields. The methodol. is atom economical and exhibits excellent tolerance towards various functional groups, and broad substrate scope. Furthermore, a one-pot procedure was developed for the sequential oxidation of benzyl alcs. and heteroaryl carbinols I (R1 = H, C(O)OMe) followed by the Pictet-Spengler cyclization and then aromatization to obtain the β-carbolines II in high isolated yields. This methodol. was found to be suitable for scale up and reusability. To the best of our knowledge, this is the first report on the oxidation of structurally diverse aryl carbinols and ODH of partially saturated N-heterocycles e.g., III using a recyclable and heterogeneous photoredox catalyst under environmentally friendly conditions. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Safety of Phenyl(pyridin-2-yl)methanone).
Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Safety of Phenyl(pyridin-2-yl)methanone
