Here, we report a chromium-catalyzed activation of acyl C-O bonds with magnesium for amidation of esters with nitroarenes. Low-cost chromium(III) chloride shows high reactivity in promoting amidation by using magnesium as reductant and chlorotrimethylsilane as additive. It provides a step-economic strategy to the synthesis of centrally important amide motifs using inexpensive and air-stable nitroarenes as amino sources.
在此，我们报道了一种铬催化的酰基C-O键与镁的活化反应，用于酯与硝基芳烃的酰胺化反应。低成本的三氯化铬在以镁作为还原剂和氯代三甲基硅烷作为添加剂促进酰胺化反应中表现出高反应活性。它为使用廉价且对空气稳定的硝基芳烃作为氨基源合成核心重要的酰胺基序提供了一种步骤经济的策略。
