Preparation of 1,2-dibromodinitroethylene and 1,1-dibromodinitroethylene
摘要:
1,2-Dibromodinitroethylene and 1,1-dibromodinitroethylene were obtained by the thermolysis of 1,1,2-tribromotrinitroethane. 1,2-Dibromodinitroethylene reacted with methanol to give methyl bromonitroacetate, and gave a Diels-Alder adduct with cyclopentadiene. 1,1-Dibromodinitroethylene reacted with ethylenediamine to give 2-(dinitromethylene)-1,3-diazacyclopentane, obtained previously from 1,1-diiododinitroethylene.
