eco-friendly and sustainable method for the tandem oxidative amidation of alcohols with amines has been reported. Using heteropolyanion-based ionic liquids as the catalyst and tert-butyl hydroperoxide as the oxidant, this amidation reaction is operationally straightforward and provides a series of primary, secondary and tertiary amides derivatives in moderate to good yields. Solvent-free media, microwave-promoted
已经报道了一种有效的,生态友好的和可持续的方法,用于醇与胺的串联氧化酰胺化。使用基于杂多阴离子的离子液体作为催化剂,使用叔丁基氢过氧化物作为氧化剂,该酰胺化反应操作简单,并以中等至良好的产率提供了一系列伯,仲和叔酰胺衍生物。无溶剂介质,微波促进条件和催化剂的可重复使用性是主要亮点。此外,在本报告中已对所提出的双功能催化机理进行了简要研究。
