Silica–Sulfuric Acid Catalyzed Nitrodeiodination of Iodopyrazoles
摘要:
We report here the synthesis of nitropyrazoles in good to excellent yields from iodopyrazoles over silica-sulfuric acid catalyst for the first time. The present procedure require less acid, offers a simplified workup procedure, and may be applied for the nitration of a wide variety of iodoazoles in drug and pharmaceutical industries.

Fifteen iodo compounds and six iodyl compounds with an iodine content between 45.3 and 89.0 % were prepared. The mono, di, and triiodyl compounds were obtained from the corresponding iodo compound by employing Oxone. All the compounds were characterized by IR, 1H and 13C NMR, elemental analysis, and differential scanning calorimetry (DSC). The impact sensitivity was measured by using BAM (Bundesamt
制备了十五种碘化合物和六种碘化合物,其碘含量在45.3%至89.0%之间。通过使用Oxone,从相应的碘代化合物获得单,二和三碘基化合物。所有化合物均通过IR,1 H和13 C NMR,元素分析和差示扫描量热法(DSC)表征。冲击敏感度通过使用BAM(BundesamtfürMaterialforschung)方法进行测量。根据计算出的地层热和实验密度,采用Cheetah 6.0预测了爆轰性能和爆轰产物。含碘物质的总百分比(wt%)(I 2,HI和气相中的I)范围为46.7(21)至88.94%(11)被发现在爆炸产物中。碘和/或含碘物种的高浓度和易获取性对于开发适合用作特工击败武器(ADW)的材料非常重要。
Synthesis of substituted-3-iodo-1H-pyrazole derivatives and their further modification under Sonogashira cross coupling reaction conditions
ethoxyethyl)-3-iodo-1H-pyrazole derivatives has been developed. During th is work protection reaction of N-H bond in substituted 3-iodo-1 H-pyrazole derivatives with ethyl vinyl ether and migration of ethoxyethyl protecting group was inves tigated. Synthetic possibilities of Sonogashira cross-coupling reactions of substituted 1-(1-ethoxy ethyl)-3-iodo-1H-pyrazole derivatives with phenylacetylene were studied
