convenient and practical method for the one-pot, three-component synthesis of terminal vinylphosphonates from readily available starting materials (aryl/alkyl/heteroaryl aldehydes, nitromethane and trialkylphosphites) through a tandem Henry–Michael reaction followed by nitro elimination in the presence of 5-hydroxypentylammonium acetate (5-HPAA) as a task-specific ionic liquid, is described. This method offers
一种方便实用的方法,用于从易得的起始材料(芳基/烷基/杂芳基醛、硝基甲烷和亚磷酸三烷基酯)通过串联亨利-迈克尔反应,然后在存在下硝基消除的情况下,一锅三组分合成末端乙烯基膦酸酯描述了作为特定任务的离子液体的 5-羟基戊基乙酸铵 (5-HPAA)。这种方法提供了几个优点,例如使用可重复使用且价格低廉的离子液体,这是一种环境友好的反应介质,以及不需要专门设备的简单反应设置。该方法在温和的反应条件下提供了良好的产物收率。
