  摘要：

  一系列N，N通过用各种易于获得的烷基化试剂对咪唑衍生物进行季铵化，然后与高度稳定且不吸湿的双（九氟丁烷-1-磺酰基）酰亚胺进行阴离子交换，可以高收率合成'-二烷基咪唑双（九氟丁烷-1-磺酰基）酰亚胺。后者通过改进的方法从氯化铵和九氟丁烷-1-磺酰氟开始获得。如此获得的季咪唑鎓盐构成了一个新的热稳定且疏水性强的离子液体亚家族，其熔点在0–40°C范围内，在水和有机溶剂（芳烃，二烷基醚）中的溶解度在0.5–1.5范围内重量％。离子液体可以很容易地从离子副产物（例如，通过水萃取，然后在高真空下彻底干燥而不会损失收率。由于上述特征，这些新的离子液体在重复催化过程中可被视为有前途的可循环介质。

  interactions with metal or its coordinated bromide and intermolecular H-bonding between heterocyclic proton with bromide are evident in some of these structures. These complexes are active in the hydrosilylation of terminal alkynes (phenylacetylene and trimethylsilylacetylene) with triethylsilane and bis(trimethylsiloxy)methylsilane. When phenylacetylene is used, the monocarbene complexes (1−3) show

Pulsed-gradient spin–echo (PGSE) NMR diffusion measurements show that the self-diffusion coefficients of the ions vary inversely with the viscosities according to the Stokes–Einstein (SE) equation. The hydrodynamic radii of the cations and anions of linear ILs calculated from the SE equation however are consistently higher than those of the corresponding branched

  AbstractEight 5‐aminotetrazolate (AT) salts based on the 1,2,3‐trimethylimidazolium (1), 1,3‐dimethylimidazolium (2), 1‐ethyl‐3‐methylimidazolium (3), 1‐butyl‐3‐methylimidazolium (4), 1‐isobutyl‐3‐methylimidazolium (5), 1‐(3′‐methylbutyl)‐3‐methylimidazolium (6), 1‐hexyl‐3‐methylimidazolium (7) and 1‐methyl‐3‐octylimidazolium (8) cations have been synthesized in high yields and fully characterized by IR and NMR spectroscopy and elemental analysis. White plate crystals of 1 were isolated in methanol/diethyl ether and crystallized. Both the AT anion and the 1,2,3‐trimethylimidazolium cation in 1 were delocalized. Differential scanning calorimetry (DSC) combined with thermogravimetric analysis (TGA) tests were used to assess the thermal stabilities of the AT salts. These salts decomposed within the temperature range 230 °C–262 °C. Salts 3–8 are very fluent room‐temperature ionic liquids, whose glass transition temperatures are low. Their viscosities at 30 °C are in the range from 92 cP to 208 cP. A correlation between the viscosity and temperature was found, and the ionic liquids to do not display an Arrhenius temperature behaviour. In addition, the standard enthalpies of formation of salts 1–8 were investigated and analyzed by the theoretical methods. Salt 2 with the 1,3‐dimethylimidazolium cation gave the highest positive enthalpy of formation. For the assessment of the energetic character of the AT salts, impact sensitivities and friction sensitivities were recorded. These AT salts are insensitive to impact (>40 J) and friction (>360 N) confirmed by UN standards. The reactions of these AT salts with 100 % HNO3 were also determined.
