The thiocarbamoylaminophosphonium salt (3) obtained from an amine (1) and TPPT (2) has been shown to be a useful synthetic intermediate for the preparation of thioureas (4), amides (10) and acylthioureas (11) by treatment with water and a carboxylic acid (9). The reaction mechanism is discussed.
从胺(1)和TPPT(2)获得的硫代氨基甲基膦盐(3)已被证明是制备硫脲(4)、酰胺(10)和酰基硫脲(11)的有用合成中间体,方法是用水和羧酸(9)进行处理。讨论了反应机制。
