- Anion ligand promoted selective C-F bond reductive elimination enables C(sp2)-H fluorination
-
A detailed mechanism study on the anion ligand promoted selective C-H bond fluorination is reported. The role of the anion ligand has been clarified by experimental evidence and DFT calculations. Moreover, the nitrate promoted C-F bond reductive elimination enabled a selective C-H bond fluorination of various symmetric and asymmetric azobenzenes to access diverse o-fluoroanilines.

- ANILINE DERIVATIVE HAVING ANTI-RNA VIRAL ACTIVITY
-
Viruses, and particularly RNA viruses, have high mutation rates. Hence, antiviral agents that have been developed to date targeting protease or reverse transcriptase of viruses have quickly lost their effectiveness and resistant viruses have emerged. Also
