Synthesis of hybrid compounds containing tetraoxane and triazole or imidazole moieties and their fungicidal activity

The research is aimed at solving one of the fundamental problems of organic chemistry — to combine groups with antagonistic properties in one molecule, viz. , an oxidizing (peroxide) group and a reducing (N-containing) group. Stable hybrid compounds containing 1,2,4,5-tetraoxane and triazole or imidazole moieties were obtained for the first time. Most of the synthesized hybrid compounds showed fungicidal activity in vitro against phytopathogenic fungi of different taxonomic classes, which is comparable or superior to the comparison preparations triadimefon and kresoxim-methyl.
