  高氯酸锂催化的三组分偶联：一种在无溶剂条件下合成 α-氨基膦酸盐的简便通用方法

  摘要：

  已开发出一种在固体高氯酸锂存在下，在无溶剂条件下合成 α-氨基膦酸盐的简单、有效和通用的方法。因此，在室温下以良好的产率相对较快地合成仲和叔α-氨基膦酸酯。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)

  A highly efficient magnetically recoverable nano-catalyst was fabricated. The material synthesized has been fully characterized by vibrating sample magnetometry (VSM), X-ray powder diffraction, scanning and transmission electron microscopy, FT-IR, and the Brunauer-Emmett-Teller (BET) isotherm method. An investigation of its catalytic activity showed it to be a unique heterogeneous Lewis acid catalyst for the synthesis of alpha-hydroxy and alpha-aminophosphonates, giving a total turnover number >= 450 for five consecutive runs. The catalyst is superparamagnetic having a 'magnetization (left behind after an external magnetic field is removed)' to 'magnetic saturation' ratio of about 0.0008, and thus could be easily separated by the use of an external magnetic field and was not agglomerated by exposure to magnetic fields.
