• Sulfonic acid supported on hydroxyapatite-encapsulated-γ-Fe2O3 nanocrystallites as a magnetically separable catalyst for one-pot reductive amination of carbonyl compounds
  作者：Jia Deng、Li-Ping Mo、Fei-Yang Zhao、Lan-Lan Hou、Li Yang、Zhan-Hui Zhang

  DOI：10.1039/c1gc15470b

  日期：——

  A novel, environmentally friendly procedure has been developed for the preparation of secondary or tertiary amines by one-pot reductive amination of carbonyl compounds using sodium borohydride in the presence of a magnetically recoverable sulfonic acid supported on hydroxyapatite-encapsulated-γ-Fe2O3 [γ-Fe2O3@HAP-SO3H] at room temperature. The catalyst was easily separated from the reaction mixture by applying an external magnet and reused for six cycles without significant loss of catalytic activity.

  Abstract Addition of dialkyl (or diaryl) phosphites to N-alkyl terephthalic Schiff bases led exclusively to a meso-form but addition to N-aryl terephthalic Schiff bases depended on the substituent of the aryl group. Semi-empirical calculations were involved to find the reason of this phenomenon.

  Matrix interference ions in low mass range has always been a concern when using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to analyze small molecules (<500 Da). In this work, a novel matrix, N1,N4-dibenzylidenebenzene-1,4-diamine (DBDA) was synthesized for the analyses of small molecules by negative ion MALDI-TOF MS. Notably, only neat ions ([M–H]-) of fatty

  当使用基质辅助激光解吸/电离飞行时间质谱（MALDI-TOF MS）分析小分子（<500 Da）时，低质量范围的基质干扰离子一直是一个令人关注的问题。在这项工作中，合成了一种新的基质N 1，N 4-二亚苄基苯-1,4-二胺（DBDA），用于通过负离子MALDI-TOF MS分析小分子。值得注意的是，只有纯离子（[M–H] -质谱中出现无基质干扰的脂肪酸，检测限（LOD）达到0.3 fmol。DBDA对氨基酸，肽和核苷酸等其他小分子也有出色的表现。此外，使用该新型基质，根据相关系数为0.99的相关曲线对血清中的游离脂肪酸进行了定量分析。此外，还进行了UV-Vis实验和分子轨道计算，以探讨DBDA在负离子模式下作为基质的机理。目前的工作表明，DBDA基质是一种高度敏感的基质，几乎没有干扰离子可用于分析小分子。同时，DBDA能够精确定量真实生物样品中的脂肪酸。 在新窗口中打开图像 图形概要 ᅟ

  promote a free radical chain process involving electron transfer by substrate activation and/or by increasing the electron affinity of the intermediate radicals. Since the adduct radicals formed from benzylideneanilines are more easily protonated than the parent Schiff bases, PTSA but not NH(4)(+) demonstrates substrate activation, although both proton donors promote the free radical reaction.

  叔丁基自由基加到亚苄基苯胺的碳原子上形成苯胺基自由基，在PTSA或NH（4）（+）在Me（2）SO中存在时将其质子化。ate络合物t-BuHgI（2）（-）易于还原生成的苯胺自由基阳离子。在没有质子供体的情况下，t-BuHgI还将氢原子转移到苯胺基上，得到还原性烷基化产物。质子化可促进自由基链过程，该过程涉及通过底物活化和/或通过增加中间自由基的电子亲和力进行电子转移。由于由苄叉基苯胺形成的加合物自由基比母体Schiff碱更容易被质子化，因此PTSA而不是NH（4）（+）表现出底物活化作用，尽管两个质子供体都促进自由基反应。
