- Biomimetic oxidation of metribuzin with hydrogen peroxide catalyzed by 5,10,15,20-tetraarylporphyrinatoiron(III) chlorides
-
The biomimetic oxidation of metribuzin, a pre- and post-emergence herbicide with hydrogen peroxide catalyzed by 5,10,15,20-tetraarylporphyrinatoiron(III) chlorides [TAPFe(III)Cl], has been studied yielding 6-t-butyl-3-methylthio-1,2,4-triazine-5(4H)-one, 4-amino-6-t-butyl-3,5(2H,4H)-dione and 6-t-butyl-1,2,4-triazin-3,5(2H,4H)-dione under various reaction conditions.

- A Contribution to the Photoinduced Desamination of 1,2,4-Triazinones
-
Solution-phase photoreactions of 4-amino-substituted 1,2,4-triazin-5(4H)-ones (1a-j) in different solvents using UV light with wavelengths greater than 290 nm have been investigated.The results show, that the desamination reaction is influenced by both oxygen and water.The photoexperiments showed clearly that OOH-radicals take part in the first step of reaction. - Key words: Photochemical Reactivity, Desamination, 1,2,4-Triazin-5(4H)-ones
