ARYLATION OF ANILINE AND AMINES BY Pd-(N-HETEROCYCLIC CARBENE) COMPLEXES
MetadataShow full item record
Aminoarenes constitute valuable building blocks in organic synthesis and an essential skeleton ubiquitously found in ligands, agrochemicals, and pharmaceuticals. This synopsis presents recent amination methods using nitrogen-heteroatom bonds as a powerful and versatile platform to rapidly synthesize diverse aminoarenes, with transition-metal catalyzed arene C-H amination. The Buchwald-Hartwig amination has been investigated theoretically and experimentally to examine the scope of possible bases under different reaction conditions. We report examples of the palladium NHC (N-heterocyclic carbene) catalyzed amination of aryl halides with anilines and amines in the presence of dimethoxyethane solvent and potassium tertiary-butoxide as a base.
