Problems solved by technology

At present, the research on new heterocycles is very active. Pyrazole heterocycles have attracted much attention due to their wide range of biological activities. Many pyrazole fungicides, insecticides, herbicides, plant growth regulators and drugs have been found. However, the bactericidal effect of the existing compounds is not good, or the toxicity is relatively large, or the preparation cost is relatively high

Meanwhile, the organic metal chelate can achieve a good effect of removing heavy metal ions from wastewater and good antibacterial effects.

Description

technical field [0001] The invention belongs to the field of organic chemistry, and particularly relates to an organometallic chelate, and also relates to a preparation method and application of the organometallic chelate. Background technique [0002] Plant diseases caused by oomycetes, especially downy mildew, vegetable gray mold, wheat head blight, wheat sheath blight, and rice blast, have a short incubation period and many re-infection times. The disease can develop rapidly and cause epidemics, and it is difficult to control. [0003] Nitrogen-containing heterocycles are a class of compounds with important application value and good biological activity. Many heterocycles have been developed into new medicines and pesticides, which play an important role in human health and agricultural production. At present, the research on new heterocycles is very active. Pyrazole heterocycles have attracted much attention due to their wide range of biological activities. Many pyrazol...
