摘要: A method is provided for the preparation of an aromatic carboxylic acid aryl ester or an N-aryl aromatic carboxamide. The method comprises contacting an O,O-diaryl thiocarbonate or an O-aryl-N-aryl thiocarbamate with a reactant that regioselectively reacts with sulfur, which contact causes an O-neophyl rearrangement, thereby forming either the aromatic carboxylic acid aryl ester or the N-aryl aromatic carboxamide, respectively.
摘要翻译: 提供了制备芳族羧酸芳基酯或N-芳基芳族羧酰胺的方法。 该方法包括使O,O-二芳基硫代碳酸酯或O-芳基-N-芳基硫代氨基甲酸酯与与硫区域选择性反应的反应物接触,所述反应物与硫接触,导致O-新茶碱重排,由此形成芳族羧酸芳酯或 N-芳基芳族羧酰胺。
