Multi-nitrobenzene substituted nitroimidazole energetic compound and preparation method thereof

The invention relates to a multi-nitrobenzene substituted nitroimidazole energetic compound with a general formula of (I). In the general formula (I), R refers to H or NH2. The invention also relates to a method for preparing the compound. The method comprises the following steps: carrying out a reaction between substituted multi-nitrobenzene chlorine and 2-azide-4-nitroimidazole, cooling to room temperature and filtering after the reaction is ended, performing methanol washing, washing and drying to obtain the compound. The synthesized energetic compound is novel in structure, mild in reaction conditions, simple in process, safe and reliable in production, simple in product after-treatment and slight in environmental harm, a special device is not required, and the basic requirements of industrial scale production are met.
