Title compds. (I;R1=C1-4 alkyl; R2=C1-12 alkyl, halogen substituted alkyl, C3-5 alkinyl, C2-4 alkenyl; X=OH, C1-4 alkyl, C1-6 alkoxy, C3-9 alkoxycarbonylalkoxy, C2-4 alkenyloxy, C3-5 alkinyloxy), useful as herbicides, were prepd. by the reaction of II and R2Z(Z=halogen). Thus, 9g 1-(2,4-dichloro-5-isopropoxphenyl)-3-methyl-Δ2-1,2,4-Tri- azolin-5- one and 9g triethylbenzylammonium chloride were suspended in 300mg benzene, and 9g NaOH soln. was added, stirred for 30 min, followed by addition of 4g bromoaryl, and refluxed for 2 hr to give 9.4g I.
