More than one kind of new compounds containing trichlorosalicylic acid methyl ester and 1,2,4-triazolopyrimidine were synthesized and synthesized based on pyrimidine derivatives. The 1 H NMR spectra and elemental analysis were used to determine The structure of the product was determined.The results of herbicidal activity showed that all of the synthesized compounds showed some activity and the activity of individual compounds on broadleaf weeds was better
