Chemistry Organic Building Blocks Fluorinated Building Blocks 1-Ethynyl-2-Fluorobenzene

1-Ethynyl-2-Fluorobenzene

These compounds have the same murcko framework: benzene,and at least 2 kinds of functional groups( —F,—C≡CH).

Electrophilic Aromatic Substitution (EAS): Fluorobenzene can undergo typical electrophilic aromatic substitution reactions, similar to benzene. The fluorine atom, being electron-withdrawing, can influence the reactivity of the benzene ring. Common EAS reactions include nitration, halogenation, sulfonation, and Friedel-Crafts reactions.
Suzuki-Miyaura Cross-Coupling: Ethynylbenzene can be used in the Suzuki-Miyaura cross-coupling reaction to form new carbon-carbon bonds with arylboronic acids in the presence of a palladium catalyst.
