An improved practical method for the photodriven diimide reduction of olefins was investigated. This catalyst-free procedure proceeds at ambient temperature, utilizes air as oxidant and a lower hydrazine loading, and produces inert nitrogen gas as the sole byproduct. Several functional groups were tolerated, and in some cases, the reaction was chemoselective. Challenging substrates such as cinnamate
研究了一种改进的用于烯烃的光驱动二酰亚胺还原的实用方法。这种无催化剂的过程在环境温度下进行,利用空气作为氧化剂和较低的肼负载,并产生惰性氮气作为唯一的副产品。几个官能团是可以容忍的,在某些情况下,反应是化学选择性的。具有挑战性的底物如肉桂酸酯衍生物和反式二苯乙烯以极好的产率减少。从家用紧凑型荧光灯泡发出的少量 UVA 射线被提议用于使二酰亚胺的顺式/反式异构化并促进氢从二酰亚胺中的损失。
