- sym-TRIAZINE DERIVATIVES. 9. REACTION OF sym-TRIAZINES CONTAINING TRICHLOROMETHYL AND ETHOXYCARBONYL GROUPS WITH PHENYLHYDRAZINE
-
Using the example of the reaction of 1,3,5-triazines simultaneously containing trichloromethyl and ethoxycarbonyl substituents with phenylhydrazine, it was shown that the presence of even one ester group leads to ring transformation.Depending on the numbe

- Use of triazine derivatives for protecting maize and sorghum plants
-
There are described triazine derivatives of the formula I STR1 wherein R1, R2 and R3 independently of one another are each C1 -C5 -alkyl which is unsubstituted or monosubstituted by C3 -C6 -cycloalkyl, or mono- or polysubstituted by halogen, or is C3 -C6 - cycloalkyl which is unsubstituted or mono- or polysubstituted by halogen, or one of the substituents R1, R2 and R3 is also halogen or --NR4 R5, in which R4 is hydrogen or C1 -C5 -alkyl and R5 is hydrogen, C1 -C5 -alkyl, monochloroacetyl or dichloroacetyl. The triazine derivatives are used for the protection of maize and sorghum plants against the harmful effects of herbicidal chloroacetanilides and chloroacetamides.

- Oligomerization of Trichloroacetonitrile (TCA) by Metal Salts
-
A CN bond was found to transform into a C=N bond under such a mild conditions as to mix trichloroacetonitrile, metal salts and methanol at 20 deg C.Ni(II) and Co(II) gave dimeric ring complexes and Mn(II) gave amidine, aminotriazine and brown powder.The aminotriazine was isolated as unstable liquid which spontaneously transformed into the crystal.A trimer structure was proposed for the liquid.In anhydrous systems, any oligomerization did not occur, so water was concluded to participate in the initiation.Keywords - trichloroacetonitrile; metal salt; methanol; nitrile; imino bond; dimeric ring complex; amidine; aminotriazine; trimer
