Beschreibung
Zusammenfassung:2-Substituted-4-alkylamino-6-( alpha , alpha -dimethyl- beta -acetyl-ethylamino-1,3,5-triazines of the general formula (I) wherein X represents chlorine or a methylthio group, R represents hydrogen or a C1-4 alkyl group, and R' stands for a C1-4 alkyl or alkenyl group, of excellent herbicidal activities are prepared as follows: cyanurchloride is reacted with diacetonamine in a molar ratio of 1:1 in an aqueous or organic solvent medium in the presence of an acid binding agent, the thus-obtained 2,4-dichloro-6-( alpha , alpha -dimethyl- beta -acetyl-ethylamino)-1,3,5-triazine is reacted with an amine of the general formula NHRR' in the presence of an acid binding agent, and if a 2-methylthio compound is to be prepared, the thus-obtained 2-chloro-4-alkylamino-6-( alpha , alpha -dimethyl- beta -acetyl-ethylamino)-1,3,5-triazine is reacted with thiourea and the obtained product is methylated, or the 2-chloro compound is reacted with methylthiol.
