  在水中方便地合成不对称N,N'-二取代硫脲

  摘要：

  已经开发出一种简单方便的两步法，用于在水中合成 25 种（其中 4 种是新型的）不对称 N,N'-二取代硫脲。烷基胺或各种取代的芳胺在室温下与氯硫代甲酸苯酯顺利反应形成硫代氨基甲酸酯，然后在回流水中与另一种烷基或芳基胺反应，得到不对称的 N,N'-二取代硫脲，产率良好至极好。该方法的主要优点是条件温和、后处理简单、收率高以及使用水作为溶剂。

  revealed the formation of aryl N‐thiocarbamoylbenzotriazoles, reactive intermediates deemed unisolable in solution. The first‐time isolation and structural characterization of these elusive molecules demonstrates the ability of mechanochemistry to access otherwise unobtainable intermediates and offers a new range of masked isothiocyanate reagents.

  Various N-aryl-N'-phenylthioureas, N, N'-diarylthioureas and N-(1, 2, 4-triazol-3-yl)-N'-arylthioureas were prepared and examined for uncoupling activities. The results indicate that substitution at the 4-position of the phenyl groups of diaryl thioureas is very important for uncoupling activities. Diphenyl thioureas substituted with two or more halogen atoms exhibited strong activities. The highest activity was exhibited by a compound containing nitro groups on both phenyl groups. These results indicate that the hydrophobicity and acidic nature of the compound are of primary importance for uncoupling activities. A remarkable decrease in activity was observed with the thioureas which were substituted with pyridine and 1, 2, 4-triazole rings. The reaction of phenyl isothiocyanate with 3-amino-1, 2, 4-triazole was also studied.

  制备并测试了各种N-芳基-N'-苯基硫脲、N,N'-二芳基硫脲和N-(1,2,4-三唑-3-基)-N'-芳基硫脲的解偶联活性。结果表明，对于解偶联活性而言，二芳基硫脲的苯基4-位取代非常重要。含有两个或更多卤素原子的二苯基硫脲表现出强烈的活性。在两个苯基上都含有硝基的化合物显示出最高的活性。这些结果表明，化合物对疏水性和酸性对于解偶联活性具有首要重要性。当硫脲被吡啶和1,2,4-三唑环取代时，活性显著下降。还研究了苯基异硫氰酸酯与3-氨基-1,2,4-三唑的反应。

  Metal-free synthesis of guanidines from thioureas under visible-light irradiation in water was successfully developed. Using 1–5 mol% of inexpensive and commercially available phenazine ethosulfate as a photocatalyst in the presence of 1 wt% cetyltrimethylammonium bromide (CTAB) as surfactant with K2CO3 as an additive base, transformations of a variety of thioureas into the corresponding guanidines under
