Azasilyl tricyclic salicylaldehyde zinc complex and its synthesis method

Abstract

The invention discloses a nitrogen-silicon tricyclic salicylaldehyde zinc complex and a synthesis method thereof. The synthesis method comprises the following steps: taking triethanolamine to react with γ-aminopropyltriethoxysilane, and the reaction product is subjected to atmospheric distillation and vacuum distillation to obtain the first intermediate product; the first intermediate product is dissolved in anhydrous tetrahydrofuran to obtain the second intermediate product A solution, dropwise adding salicylaldehyde or 3-substituted salicylaldehyde or 4-substituted salicylaldehyde into the first solution, react at room temperature, and precipitate crystals after cooling, and process the precipitated crystals through a mixed solution of benzene and ether recrystallization to obtain recrystallization, and purification to obtain the second intermediate product; take zinc acetate and dissolve it with anhydrous methanol to obtain the second solution, get the second intermediate product and dissolve it with anhydrous tetrahydrofuran to obtain the third solution, and mix the second solution with The third solution is mixed and then reacted to precipitate solid matter, which is purified to obtain the zinc complex of azasilazine tricyclic salicylaldehyde. The synthesis method has low cost, few by-products and little environmental pollution.

Description

technical field [0001] The invention relates to a nitrogen silicon tricyclic salicylaldehyde zinc complex and a synthesis method thereof. Background technique [0002] Azasilatricyclic compounds have immune enhancement and anti-tumor effects, and have obvious effects on promoting cell proliferation and wound healing. Asazo-silicon tricyclic compounds such as some Schiff bases not only have good bactericidal and anticancer effects, but also have analgesic, anti-inflammatory, antibacterial and sterilizing, antiviral and other activities. The N atom of N has a lone pair of electrons, so various functional groups can be introduced into the Schiff base structure to derivatize it, which is unique in application. Salicylaldehyde has analgesic, anti-inflammatory, antibacterial, sterilizing, and antiviral activities, and is an effective herbicide, insecticide, and fungicide. At present, in the field of complexes, the synthesis of azanitrosilicon tricyclic compounds and salicylaldeh...
