  An organic light emitting device (OLED) that includes an anode, a cathode, and an organic layer disposed between the anode and the cathode. The organic layer includes a metal compound that comprises a ligand L A of Formula I, wherein the dashed lines represent coordination to a metal M. The metal M is selected from the groups consisting of Os, Ru, Ir, Rh, Pt, Pd, and Cu, and the metal is further coordinated to one or more ligand(s) L B , wherein the ligand(s) L B can be the same or different if more than one ligand L B is present. Optionally one or two of the ligand(s) L B can independently link to the ligand L A through one of R 1 to R 5 . The invention is also directed to a consumer product that includes an OLED, and the OLED includes an organic layer that includes a metal compound that comprises a ligand L A of Formula I.

  In order to improve the desulfurization efficiency, an ionic liquid (IL) was used as the solvent for the desulfurization of diesel fuel with nickel boride. The nickel boride prepared in IL–H2O showed high specific surface area. The desulfurization efficiency of model organosulfur compounds in this work was higher than that in the previous studies. The desulfurization reactivity of model organosulfur compounds followed the order of BT (DBT) > 3-MBT > 4,6-DMDBT. Furthermore, the products of model organosulfur compounds after desulfurization were analyzed by GC/MS and their corresponding reaction routes were proposed. The effectiveness of nickel salts followed the order of NiCl2 (Ni(OAc)2) > NiSO4 > Ni(NO3)2. The desulfurization efficiency of model diesel fuels reached 90.6% under the conditions of B/S molar ratio = 9, Ni(OAc)2/S molar ratio = 3, oil/IL volume ratio = 3, water content in IL = 5%, and reaction time = 50 min. ILs maintained their original structures after regeneration. Finally, the desulfurization of real diesel fuel was carried out and a desulfurization efficiency of 88.6% was obtained in 50 min.

  为了提高脱硫效率，使用离子液体（IL）作为硼化镍对柴油进行脱硫的溶剂。在 IL-H2O 中制备的硼化镍显示出较高的比表面积。与之前的研究相比，本研究中模型有机硫化合物的脱硫效率更高。模型有机硫化合物的脱硫反应性依次为 BT (DBT) > 3-MBT > 4,6-DMDBT。此外，还利用 GC/MS 分析了模型有机硫化合物脱硫后的产物，并提出了相应的反应路线。镍盐的有效性顺序为 NiCl2 (Ni(OAc)2) > NiSO4 > Ni(NO3)2。在 B/S 摩尔比 = 9、Ni(OAc)2/S 摩尔比 = 3、油/IL 体积比 = 3、IL 中水含量 = 5%、反应时间 = 50 分钟的条件下，模型柴油的脱硫效率达到 90.6%。IL 在再生后保持了原有结构。最后，对实际柴油进行了脱硫处理，在 50 分钟内脱硫效率达到 88.6%。

  The title reactions can be explained by Wagner–Meerwein rearrangement of α-thio carbocations (thionium ions) to β-thio carbocations; this unusual reactivity may be due to superelectrophilic activation by aluminium chloride.

  标题反应可以用δ-硫代碳基（噻吩离子）到δ-硫代碳基的瓦格纳-梅尔韦恩重排来解释；这种不寻常的反应性可能是由于氯化铝的超亲电活化作用。

  at the catalyst surfacewas not the rate-determining step for their transformation. Ourresults imply that the hydrodesulfurization of these compounds occurson one single type of sites by a flat adsorption, leading to apreliminary partial hydrogenation of one aromatic ring. Variationsin reactivities of the dibenzothiophene derivatives were thus explainedby different reaction rates for the C–S bond scission

  在工业NiMo / Al 2 O 3上的间歇反应器中研究了二苯并噻吩，4-甲基-二苯并噻吩，4,6-二甲基二苯并噻吩和2,8-二甲基二苯并噻吩的转化机理。在氢气压力5 MPa下于573 K进行加氢处理催化剂。包括竞争性催化实验在内的详细机理研究证明，大多数难熔分子在催化剂表面的吸附不是决定其转化速率的步骤。我们的结果暗示，这些化合物的加氢脱硫通过平面吸附发生在一种单一类型的位点上，从而导致一个芳香环的初步部分氢化。因此，二硫代噻吩衍生物的反应性变化是由于硫原子附近甲基取代产生的位阻引起的C–S键断裂的不同反应速率而引起的。
