Our first reaction employed aqueous ammo-nium hydroxide on the assumption that the azeotropic removal of water, which is necessary for the formation of the presumed iminium ion intermediate, would enable the net delivery of ammonia that would react with the anhydride. 基于恒沸除水的假设，我们在第一个反应中使用水合氢氧化铵。这对预期的亚胺离子中间体的形成非常必要，并且能促进与酐反应的氨水产生净传递。 |
