The present invention provides an inexpensive one-step method for preparing an aromatic carboxamide, such as a phenyl substituted carboxamide) by reacting an aromatic amine (e.g. a phenylamine) and a carboxylic acid (e.g. an alkanoic acid or ester thereof) in the presence of a boron containing compound (e.g. boronic acid or boric acid) and, optionally, a chelating agent (e.g. a 2-pyridinylamine).
本发明提供了一种廉价的一步法制备芳香族羧酰胺(例如苯基取代的羧酰胺)的方法,通过在含有硼化合物(例如硼酸或硼酸酯)和(可选的)螯合剂(例如2-吡啶基胺)的条件下,反应芳香族胺(例如苯胺)和羧酸(例如脂肪酸或其酯)。
