Triazole-containing compounds of structure and its preparation method and use as herbicides

The invention discloses a compound comprising a triazole structure, a preparation method thereof and an application of the compound taken as a weed killer. The structure formula of the compound comprising the triazole structure is shown in a formula I, R represents allyl, alkyl acyl with a carbon atom number of 1-20, substituted or un-substituted benzoyl, O, O-dimethyl phosphoroamido-thioate, phenyl, benzene oxygen acetyl, 3-phenyl-2 acryl or 2, 6-binitro-4-trifluoro methyl phenyl. The preparation method of the compound shown in the formula I comprises the steps as follows: under the catalytic action of alkali, 3-amino-1 H-1, 2, 4-triazole and an electrophilic reagent are subjected to electrophilic substitution reaction, so that the compound shown in the formula I is obtained. The weed killer can be used for preventing and killing weeds, green bristle grass, crab grass, eleusine indica, black nightshade, amaranth, piemarker, quinoa, scandent hop, summer cypress, field bindweed, acalypha australis, Ixeris chinensis and viola prionantha.
