Preparation method of multiple iodo-4,4'-di-1,2,4-triazole derivatives

The invention discloses a synthesis method of multiple iodo-4,4'-di-1,2,4-triazole derivatives. Multiple iodo-4,4'-di-1,2,4-triazole derivatives are generated through reaction by taking 4,4'-di-1,2,4-triazole as a raw material and iodine and iodine chloride as iodo reagents respectively. According to the method disclosed by the invention, multiple iodo-4,4'-di-1,2,4-triazole derivatives are generated through an electrophilic substitution reaction by taking 4,4'-di-1,2,4-triazole as the raw material and iodine and iodine chloride as the iodo reagents respectively. The synthesis method of the iodo-4,4'-di-1,2,4-triazole derivatives disclosed by the invention has the advantages of convenience in operation, low cost, controllability in technology and the like, and can be used for preparing multiple 4,4'-di-1,2,4-triazole derivatives.
