5-Substitutedtetrazoles were prepared by treatment of nitriles with sodium azide and triethylammonium chloride in nitrobenzene in a microwave reactor. This practical method combines the advantages of previous procedures, including good-to-excellent yields, short reaction times, and easy isolation of the product. Moreover, sterically hindered tetrazoles, as well as those deactivated by electron-donating

evaluated. The enthalpy of formation calculated using quantum chemical methods is in an excellent agreement with the experimental value. The thermodynamicproperties of 5-(1-adamantyl)tetrazole in the ideal-gas state were calculated in the temperature range from (0 to 1000) K. The calculated entropy of gaseous 5-(1-adamantyl)tetrazole is in a good agreement with the one obtained from the experimental data
摘要 在真空绝热量热计中研究了 5-(1-金刚烷基)四唑的热容在 (5 和 370) K 之间的温度依赖性。根据获得的数据,在 (0–370) K 范围内评估了化合物在缩合状态下的热力学性质。 5-(1-金刚烷基)四唑的晶体结构由 X 射线衍射分析确定。结晶5-(1-金刚烷基)四唑在(394-419)K温度范围内的饱和蒸气压通过Knudsen渗出法测量,并使用这些结果获得其升华焓。在 298.15 K 下结晶 5-(1-金刚烷基)四唑的标准生成焓是在静态弹式燃烧量热计中测定的。根据这些数据,评估了气态 5-(1-金刚烷基)四唑的标准生成焓。使用量子化学方法计算的生成焓与实验值非常吻合。计算了理想气态 5-(1-金刚烷基)四唑在 (0~1000)K 温度范围内的热力学性质。 气态 5-(1-金刚烷基)四唑的计算熵符合良好与从实验数据中获得的。
Efficient Transformation of Inactive Nitriles into 5-Substituted 1H-Tetrazoles Using Microwave Irradiation and Their Applications
Efficient transformations of inactive nitriles into 5-substituted 1H-tetrazoles in DMF in a microwave reactor are described. The present method is applied to the synthesis of tetrazolato-bridged dinuclear platinum(II) complex and tetrazole C-1-ribonucleoside phosphoramidite.
