Uses

Used in Agrochemical Industry:
4-Methoxy-6-(trifluoromethyl)-1,3,5-triazin-2-amine is used as a reactant/reagent for the preparation of N-phenylsulfony-N''-pyrimidinylureas, which are a class of herbicides. These herbicides are effective in controlling a wide range of weeds, thereby enhancing crop yield and quality. The unique structure of 4-methoxy-6-(trifluoromethyl)-1,3,5-triazin-2-amine contributes to the herbicidal activity and selectivity of the final products.

A ZnCl2 - Catalysed synthesis of 2-amino-4-trifluoromethyl-6-methoxy- 1,3,5-triazine

2-Amino-4-trifluoromethyl-6-methoxy-1,3,5-triazine can be easily prepared starting from cyanoguanidine by a zinc chloride catalysed process.

Preparation of asymmetrically substituted triazines

A process for preparing asymmetrically substituted triazines of the formula I STR1 where R1 is hydrogen, methyl or ethyl, R2 and R3 independently of one another are an unsubstituted or substituted hydrocarbon radical, by reaction of a cyanoguanidine of the formula II STR2 with a carboxylic acid derivative in the presence of an alcohol of the formula III which comprises reacting a carboxylic acid ester of the formula IV where R3 has the abovementioned meaning and R4 is an unsubstituted or substituted hydrocarbon radical, in the presence of a base or of a carboxamide selected from the group consisting of N,N-dialkylformamide, N,N-dialkylacetamide and N-methylpyrrolidone and in the presence of a salt or of a salt-like compound of the elements magnesium, calcium, aluminum, zinc, copper, iron, cobalt, nickel or chromium, is described.

Preparation of 6-trifluoromethyl-1,3,5-triazines

6-Trifluoromethyl-1,3,5-triazines I STR1 (X=O,S; R1 =H; R1, R2 =carbon organic radicals) are prepared by reacting (a) N-trichloroacetamidinoguanidines II STR2 with trifluoroacetic acid derivatives III (Y=Cl, alkoxy, CF3 --CO--O) to give 4-trichloromethyl-6-trifluoromethyl-1,3,5-triazines IV STR3 and (b) reacting the products IV in the presence of a base with alcohols V The triazines I are valuable intermediates for crop protection agents.
