No catalyst required! A highly efficient, catalyst‐free process to generate diimide in situ from hydrazine monohydrate and molecular oxygen for the selective reduction of alkenes has been developed. The use of a gas–liquid segmented flow system allowed safe operating conditions and dramatically enhanced this atom‐economical reaction, resulting in short processing times.
无需催化剂!已开发出一种高效,无催化剂的方法,该方法可从一水合肼和分子氧原位生成二酰亚胺,以选择性还原烯烃。气液分段流系统的使用允许安全的操作条件,并大大增强了这种原子经济反应,从而缩短了处理时间。
