A preparative one-step method for the synthesis of 1,1,1,5,5,5-hexafluoro-4-trifluoromethylpentane-2,3-dione dihydrazone from perfluoro-4-methylpent-2-ene and hydrazine hydrate has been developed. Oxidation of this dihydrazone with bromine in water gives 3-diazo-1,1,1,5,5,5-hexafluoro-4-trifluoromethylpentane-2-one. The same product is obtained from 3-hydrazono-1,1,1,5,5,5-hexafluoro-4-trifluoromethylpentane-2-one
开发了一种从全氟-4-甲基戊-2-烯和水合肼合成1,1,1,5,5,5-六氟-4-三氟甲基戊烷-2,3-二酮二腙的制备性一步法. 该二腙在水中用溴氧化得到 3-diazo-1,1,1,5,5,5-hexafluoro-4-trifluoromethylpentane-2-one。在类似条件下,从 3-hydrazono-1,1,1,5,5,5-hexafluoro-4-trifluoromethylpentane-2-one 得到相同的产物。
