  摘要：

  本文公开了使用简单烷基胺作为氨基源的铜（II）介导的惰性C（sp 3）H键的螯合分子间胺化反应。因此，提供了α，α-二取代的β-氨基酸衍生物的直接且经济的步骤。该反应具有良好的官能团耐受性和相对较宽的底物范围。此外，吗啉和自由基抑制剂的2,6-二-之间的偶联产物叔丁基- p甲酚（BHT）分离，表明单电子转移（SET）进程可能在这一转变有关。

• METHOD FOR PREPARING QUATERNARY PHOSPHONIUM SALTS

  A two-step pathway for preparing high pure quaternary phosphonium salts is disclosed. In the first step, hydrogen phosphide (PH 3 ) or a higher phophine reacts with a protonic compound to produce a phosphonium salt, which then reacts with a carbonic acid diester to produce a quaternary phosphonium salt in the second step. On one hand, hydrogen phosphide (PH 3 ) and higher phophines, including primary phosphines, secondary phosphines, and tertiary phosphines, after neutralization with protonic compound, become sufficiently reactive and can be alkylated by carbonic acid diester to form quaternary phosphonium cations. On the other hand, as an anion-exchange procedure is completely avoided, the process not only gives quaternary phosphonium salts of high purity, but also gives people freedom to design the cation and the anion of a quaternary phosphonium salt synchronously by choosing a preferred phosphine and a protonic compound that can supply a desired anion.

  揭示了一种制备高纯度四元磷铵盐的两步途径。在第一步中，氢磷化物（PH3）或更高的磷化物与质子化合物发生反应，产生磷铵盐，然后在第二步中与碳酸二酯发生反应，产生四元磷铵盐。一方面，氢磷化物（PH3）和更高的磷化物，包括一次磷化物、二次磷化物和三次磷化物，在与质子化合物中和后变得足够活性，可以被碳酸二酯烷基化形成四元磷铵阳离子。另一方面，由于完全避免了阴离子交换程序，该过程不仅提供高纯度的四元磷铵盐，还使人们可以通过选择理想的磷化物和可以提供所需阴离子的质子化合物，同时设计四元磷铵盐的阳离子和阴离子。

  Some implementations of the present disclosure prevent, reduce or at least slow equipment fouling using passivation as a treatment prior to contacting metallic components with hydrocarbon containing fluid, that is, an environment where fouling occurs. For example, one implementation includes a method of passivating heat exchangers in a SAGD process or system using the compositions and compounds of the present disclosure. The composition may be applied to a component prior to its first inclusion in an online system or following placing the system offline for maintenance. The composition may be used to treat metallic equipment surface(s), for example, via contacting them with a suspension or solution of the composition described herein, prior placing the system online. The method may further include treatment of the process fluid, for example, via injection or batch treatment of the composition with the compositions described herein into the process fluid.
