5-IODOTETRAZOLE DERIVATIVES, SYNTHESIS METHOD THEREOF, FUNGICIDAL AGENT BASED ON SAID DERIVATIVES, DISPERSION PAINT MATERIAL CONTAINING SAID DERIVATIVES, METHOD OF PROTECTING PLANTS AND DISPERSION PAINT MATERIALS FROM ATTACK AND/OR DECOMPOSITON BY FUNGI Russian patent published in 2011 - IPC A01N43/713 C07D275/04 C09D5/14 

FIELD: chemistry.

SUBSTANCE: invention relates to fungus control, specifically to 5-iodotetrazole derivatives , in which R¹ denotes butylene, straight unsubstituted alkyl with 8-16 carbon atoms, straight or branched unsubstituted or mono- or multi-, identically or differently substituted alkyl with 1-8 carbon atoms, where the substitutes are or mono- or multi-, identically or differently substituted alkyl residues selected from a group comprising unsubstituted alkoxy or 1-6 carbon atoms and alkoxy with 1-6 carbon atoms, substituted with dioxalonyl, phenyl which is up to five times identically or differently substituted with halogen, alkyl with 1-4 carbon atoms, halogenalkyl with 1-4 carbon aotms, alkoxy with 1-3 carbon atoms, alkylthio with 1-4 carbon atoms, morpholinyl, except the following compounds: 1-tert-butyl-5-iodotetrazole, 1-ethyl-5-iodotetrazole, 1-methyl-5-iodotetrazole. Said 5-iodotetrazole derivatives are obtained by treating tetrazoles of general formula , in which R¹ assumes values given above, with iodine in an organic solvent in the presence of a base and, if needed, in the presence of a diluent. The invention also relates to a fungicidal agent, containing 5-iodotetrazole derivatives of general formula , in which R¹ denotes hydrogen, alkylene with 1-4 carbon atoms, straight unsubstituted alkyl with 8-16 carbon atoms, straight or branched unsubstituted or mono- or multi-, identically or differently substituted alkyl with 1-8 carbon atoms, where the substitutes are mono- or multi-, identically or differently substituted alkyl residues selected from a group comprising unsubstituted alkoxy with 1-6 carbon atoms and alkoxy with 1-6 carbon atoms, substituted dioxalonyl, unsubstituted phenyl, phenyl which is up to five times identically or differently substituted with halogen, alkyl with 1-4 carbon atoms, halogenalkyl with 1-4 carbon atoms, alkoxy with 1-3 carbon atoms, alkylthio with 1-4 carbon atoms, morpholinyl and at least one solvent or diluent, as well as auxiliary additives if necessary. The invention also relates to paint material containing compounds of formula (Ia).

EFFECT: said fungicidal agent can be used in a method of protecting plants and paint materials from attack and/or decomposition by fungi by exposing the fungi or habitat thereof to the said agent.
