Compounds of the formula (I) or salts thereof are suitable for preparing active substances from the from the class of the aminotriazines of the formula (IV), for example herbicidal active substances. The compounds (I) can be prepared by chlorinating compounds of the formula (II) where, in the formulae, R1, R2, R3 and X are as defined in claim 1 and A and R have the meaning required in the active substances to be prepared, and they can be reacted with amines of the formula A—NH—R to give the active substances.
The Synthesis of Alkyl- and Aryl-Substituted 1,3,5-Triazines

The reaction of chloromethyleneiminium salts with N-cyanoamidines provides a new and versatile route to alkyl- and aryl-substituted 1,3,5-triazines.Variation of substituents in the starting materials allows the synthesis of monoaryl-, diaryl-, alkyl-aryl- and certain mono- and di-alkyl-1,3,5-triazines bearing a variety of other substituents including hydrogen, chlorine and O-, S- and N-radicals.The generally good yields, ready availability of starting materials, and the scope and facility of the reaction make it the method of choice for the synthesis of 1,3,5-triazines with these substitution patterns.
