Home Chemistry Heterocyclic Building Blocks Pyridines 2-Bromo-4-Methylpyridine
Substitution Reactions: The bromine atom on the pyridine ring can be substituted with other functional groups through nucleophilic aromatic substitution (SNAr) reactions. For example, substitution with a nucleophile like a primary amine can yield an N-alkylated or N-aryl pyridine.
Metalation Reactions: The bromine atom can be replaced with a metal atom using appropriate metalation reagents. This can lead to the formation of organometallic complexes which can further participate in various reactions.
Cross-Coupling Reactions: The bromine atom can undergo palladium-catalyzed cross-coupling reactions such as Suzuki, Heck, or Stille coupling, enabling the synthesis of biaryl compounds or other functionalized pyridines.
Reduction Reactions: The bromine atom can be reduced to an alkyl group or a hydrogen atom using reducing agents like lithium aluminum hydride (LiAlH4) or hydrogen gas over a metal catalyst.
Oxidation Reactions: The methyl group or the pyridine ring can undergo oxidation reactions to yield corresponding ketones, aldehydes, or carboxylic acids.
Ring-Closure Reactions: Under suitable conditions, it can participate in ring-closure reactions leading to the formation of heterocyclic compounds.
