Copper-catalyzed amidation of acids with formamides or acetamide for the selective synthesis of amides with the aid of 1,4-diazabicyclo[2.2.2]octane as the ligand and tert-butyl hydroperoxide as the oxidant is presented. This method is highly compatible with a wide range of acids, including alkyl acids, aryl acids, α,β-unsaturated acids, and amino acids.
铜催化的酸与甲酰胺或乙酰胺的酰胺化反应,在 1,4-二氮杂双环 [2.2.2] 辛烷作为配体和叔丁基过氧化氢作为氧化剂的帮助下选择性合成酰胺。该方法与多种酸高度兼容,包括烷基酸、芳基酸、α,β-不饱和酸和氨基酸。
