TRIAZENE DERIVATIVE, PRODUCTION THEREOF AND AGRICULTURAL AND HORTICULTURAL FUNGICIDE CONTAINING SAID DERIVATIVE AS ACTIVE COMPONENT

摘要

NEW MATERIAL:A triazene derivative of formula I (X is halogen; Y is lower alkyl, lower alkoxyl or OH; R is lower alkynyl). EXAMPLE:1,1-Dimethyl-3-(3-chloro-4,5-dipropargyloxyphenyl)triazene. USE:An agricultural and horticultural fungicide. It exhibits strong selective fungicidal effect against phytopathogenic fungus and other mold resistant to cyclic imide fungicides. PREPARATION:The compound of formula I can be produced by diazotizing the aniline derivative of formula II and reacting the obtained diazonium salt with the secondary amine of formula III.
