oxidizing agent (brominations can be achieved in hydrobromic acid). When olefins are chosen as substrates, two Cl atoms are added to the double bond in an anti fashion, while hydrochlorination products are formed simultaneously. According to the products observed in both types of reactions for various substrates in this 3-phase system, the halogenations proceed via electrophilic pathways.
如果存在O 2作为氧化剂,则RuCl 3在浓
盐酸中的溶液能够催化
氯化芳族化合物(
溴化可以在
氢溴酸中实现)。当烯烃被选作底物,两个
氯原子加到双键以反的方式,虽然氢
氯化产物同时形成。根据在该三相系统中针对各种底物的两种反应类型中观察到的产物,卤化通过亲电途径进行。
