A metal‐free, one‐pot synthesis of 1,2‐naphthoquinone was accomplished from 2‐naphthol by utilizing economically cheap NBS under open air conditions. Initial formation of 1,1‐dibromonaphthalen‐2‐one and subsequent transformation afforded the 1,2‐naphthoquinone. This oxidation was completed within 30 min and had broad substrate scope. Moreover, this system tolerated heterocyclic systems and was also
通过在露天条件下利用经济实惠的NBS,由2-萘酚完成了无金属的一锅法合成1,2-萘醌的合成。1,1-二溴萘-2-酮的最初形成和随后的转化提供了1,2-萘醌。该氧化在30分钟内完成,并具有广泛的底物范围。此外,该系统可耐受杂环系统,也适用于1,3-二羰基系统。这种反应时间短,后处理简单且对湿气不敏感的实用方法可能会取代昂贵且有害的氧化剂和金属试剂的使用。
