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.
提供了一种制备芳香羧酸芳基酯或N-芳基芳香羧酰胺的方法。该方法包括将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能够选择性地与硫反应的试剂接触,这种接触导致O-新叶基重排,从而分别形成芳香羧酸芳基酯或N-芳基芳香羧酰胺。
