  铁掺杂单壁碳纳米管是无溶剂条件下合成有机磷化合物的有效且可重复使用的多相催化剂

  摘要：

  掺杂铁的单壁碳纳米管（Fe / SWCNT）是一种高效，环保且可重复使用的非均相催化剂，用于在无溶剂条件下通过胺，羰基化合物和磷化合物的多组分反应合成装饰多样化的α-氨基膦酸酯。该方法论证了非常简单的方法，具有广泛的适用性，将范围扩展到脂族和芳族胺和羰基化合物。它也使得在羰基化合物，丙二腈和磷化合物反应过程中一锅法合成β-膦酰基丙二酸酯成为可能。在每种情况下均获得了优异的结果，从而以良好的收率提供了相应的有机磷加合物。

  5-Hydroxypentylammonium acetate as a task-specific ionic liquid promotes efficient tandem Knoevenagel-phospha-Michael reaction of phosphite esters with aryl/heteroaryl/alkyl/salicylaldehydes and malonitrile/ethyl cyanoacetate at room temperature in short reaction times. This simple procedure allows a series of β-phosphonomalonates and 4-substituted 2-amino-4H-chromenes with phosphonic acid dialkyl esters to be synthesized in good to high yields in the presence of an ionic liquid for the first time.
