On May 15, 2020, Balayeva, Narmina O.; Mamiyev, Zamin; Dillert, Ralf; Zheng, Nan; Bahnemann, Detlef W. published an article.Application of 79815-20-6 The title of the article was Rh/TiO2-Photocatalyzed Acceptorless Dehydrogenation of N-Heterocycles upon Visible-Light Illumination. And the article contained the following:
Rh-photodeposited TiO2 nanoparticles selectively dehydrogenate N-heterocyclic amines I (R1 = H, 6-Me, 7-OH, etc.; R2 = H, 2-Me, 2-Ph-4-MeS), II (R3 = H, 6,7-dimethoxy; R4 = H, Ph, Me) and III (R5 = H, trifluoromethyl; R6 = H, Me, COOH, COOMe, etc.) with the concomitant generation of mol. hydrogen gas in an inert atm. under visible light (λmax = 453 nm) illumination at room temperature Initially, a visible-light-sensitive surface complex is formed between the N-heterocycle and TiO2. The acceptorless dehydrogenation of N-heterocycles is initiated by direct electron transfer from the HOMO energy level of the amine via the conduction band of TiO2 to the Rh nanoparticle. The reaction condition was optimized by examining different photodeposited noble metals on the surface of TiO2 and solvents and finding that Rh0 is the most efficient cocatalyst, and 2-propanol is the optimal solvent. Structurally diverse N-heterocycles such as tetrahydroquinolines I, tetrahydroisoquinolines II, indolines III, and others bearing electron-deficient as well as electron-rich substituents underwent the dehydrogenation in good to excellent yields. The amount of released hydrogen gas evinces that only the N-heterocyclic amines are oxidized rather than the dispersant. This developed method demonstrates how UV-active TiO2 can be employed in visible-light-induced synthetic dehydrogenation of amines and simultaneous hydrogen storage applications. The experimental process involved the reaction of H-Idc-OH(cas: 79815-20-6).Application of 79815-20-6
