  摘要：

  本文报道的是吡唑导向的铱催化的对位氮原子中心的无偏亚甲基CH键的对映选择性硼化。手性双齿硼基配体，铱前体和吡唑导向基团的结合是观察到的高区域选择性和对映选择性的原因。该方法耐受大量官能团，以提供具有良好至优异对映选择性的相应C（sp 3）-H功能化产物。

  effect of doping in solvents with low Up, [BMIM][BF4], DMSO, and DMF were selected. The conversions for toluene doped with [BMIM][BF4], DMSO, and DMF were 100%, 59%, and 25%, respectively. These conversions were greater than when done in just toluene (46%). Thus, [BMIM][BF4] was the best polar doping solvent, followed by DMSO. DMF was not considered to be a satisfactory doping solvent. No conversion was

  在超声探头设备中确定25种溶剂的加热曲线，振幅为20％，25％和30％。每种溶剂根据其沸点加热。评估了蒸汽压，表面张力和溶剂粘度在耗散的超声功率（Up）中的影响。这些溶剂特性和耗散Up的多元回归分析表明，溶剂粘度是影响最大的耗散Up的特性。涉及掺有[BMIM] [BF4]的乙腈的实验表明，加热速度比MeCN快。在超声条件下，在吡唑的N-烷基化反应中测试了非质子极性溶剂（例如DMSO，DMF和MeCN）。在90℃下5分钟后，反应物已在这些溶剂中完全转化为产物。测试了具有低耗散Up的溶剂（例如甲苯）。与非质子极性溶剂相比，转化率较低。当反应在己烷中进行时，未观察到转化成产物。为了检查在低Up溶剂中掺杂的效果，选择了[BMIM] [BF4]，DMSO和DMF。掺杂有[BMIM] [BF4]，DMSO和DMF的甲苯的转化率分别为100％，59％和25％。这些转化率要比仅使用甲苯时的转化率高（46％）。因此，[BMIM]

  Even after more than 50 years since its discovery, the electrophilic potential of diazirines was never truly exploited. This longstanding limitation has been resolved. N-Monosubstituted diaziridines and hydrazones are obtained by nucleophilic additions. They release, under hydrolysis conditions, the corresponding monosubstituted hydrazines. The latter were converted to pyrazoles in high yields. The
