Phenylphosphonic acid is an efficient, friendly and reusable heterogeneous catalyst for the synthesis of α-aminophosphonates through a ‘one-pot’ three-component reaction of amines, carbonyl compounds and dialkyl phosphites under solvent-free conditions. This methodology illustrates a very simple procedure, with wide applicability, extending the scope to aliphatic and aromatic amines, aliphatic and
苯基膦酸是一种高效、友好且可重复使用的多相催化剂,用于在无溶剂条件下通过胺、羰基化合物和亚磷酸二烷基酯的“一锅法”三组分反应合成 α-氨基膦酸酯。该方法说明了一个非常简单的程序,具有广泛的适用性,将范围扩展到脂肪族和芳香族胺、脂肪族和芳香族醛以及脂肪族酮。它还能够大规模合成 α-氨基膦酸盐,清洁转化,易于后处理和纯化。在每种情况下都获得了优异的结果,以中等至良好的产率获得了所需化合物。
