Abstract An efficient visible‐light‐induced α‐oxidation of N ‐substituted tetrahydroisoquinolines to dihydroisoquinolones has been developed using eosin Y as an organo‐photocatalyst and oxygen a green oxidant. The reactions were carried out under mild reaction conditions; the desired obtained in up 96% yield at room temperature atmosphere. This transformation provides convenient route with wide range substrates. magnified image
Abstract A visible‐light‐promoted synthesis of quinoxalin‐2(1 H )‐ones has been developed using 9‐mesityl‐10‐methylacridinium perchlorate as an organo‐photocatalyst. The atmosphere‐controlled method (Ar/air) enabled the selective hydroxyl‐ and acyl‐containing under mild reaction conditions without use any metal catalysts or toxic reagents. fluorescent labelling experiment showed that hydroxyl‐containing may have utility in various biological applications potent fluorophores. magnified image
Biaryls were synthesized via a novel visible-light-promoted Gomberg-Bachmann reaction that does not require photosensitizer or any metal reagents. The formation of an electron donor-acceptor complex between aryl diazonium salts and pyridine allows, under visible-light irradiation, the synthesis biaryls in moderate-to-high yields.
The oxidative cleavage reaction of the C–S bond using singlet oxygen is challenging because its uncontrollable nature. We have developed a novel method for singlet-oxygen-mediated selective silver(II)–ligand complexes. Visible-light-induced silver catalysis enables controlled benzyl thiols to afford carbonyl compounds, such as aldehydes or ketones, which are important synthetic components.
Isostructural trivalent lanthanide and actinide amidinates bearing the N,N'-bis(isopropyl)benzamidinate (iPr2BA) ligand [LnIII/AnIII(iPr2BA)3] (Ln = La, Nd, Sm, Eu, Yb, Lu; An U, Np) have been synthesized characterized in both solid solution states. All compounds were examined state utilizing single crystal X-ray diffraction (SC-XRD), revealing a notable deviation series with shortened bond lengths compared to trend series, suggesting nonionic contribution actinide–ligand bonding....
A visible-light-mediated oxidative C–S bond cleavage of benzyl thiols through an in situ activation strategy was developed.
