In 1887, chemist Sir Arthur Michael reported a nucleophilic addition reaction to the β-position of α,β- unsaturated carbonyl compounds. These reactions, named Michael addition reactions, have been ...

Arynes are known to serve as highly reactive benzene-based synthons, which have gained numerous successes in preparing functionalized arenes. Due to the superb electrophilic nature of these fleeting ...

Radical reactions, distinct from polar reactions, offer unique advantages such as exceptional chemoselectivity and remarkable tolerance of functional groups 7,8,9. The Giese-type addition reaction, ...
