The various components of your paper [title, text, heads, etc.] are already defined on the style sheet, as illustrated by the portions given in this document. 1,2,3- triazoles compounds is important N- heterocyclic compounds, in recent years has been widely used in industrial production, R&D, materials science and other fields. Therefore, the paper take dichlorobenzene and difluorobenzene as raw material use some high-quality sterilization group of triazole fungicide; synthesize a series of triazole compounds. In the synthetic reaction, compounds R1, R2, R3 have not been reported, their structures were confirmed by 1H-NMR, MS and FT-IR analysis, the properties of compounds synthesized were stable, long-term placement had no change in appearance. At the same time, we study the inhibition ability of fungi. The results showed that: inhibition ability of compound R1 was the strongest on mildew and rots fungi; compound R2 has equal inhibition ability for tebuconazole; the other compounds were showed no obvious bacteriostatic effect.
