Efficient photoreduction of triazines with aliphatic amines

open access: yes, 2002
Aliphatic amines are used as powerful electron donators in electrontransfer reactions of electronically excited aromatic amines. In triazines the LUMO energy is decreased compared to benzene, therefore these electron-poor compounds are easily reduced and

Advances in chemistry and biological activity of fluorinated 1,3,5-triazines

open access: yes, 2007
The substitution of hydrogen by fluorine as bioisosteric replacement has been practised widely in agricultural and medicinal chemistry. This has led to the discovery of many pesticides and therapeutically useful chemical entities.
