Ketone with amine reaction
Web1 dag geleden · Direct coupling of unactivated olefins with primary alkylamines is considered to be an efficient but unknown method for the construction of complex amines. Herein we report a catalytic intermolecular oxidative amination of unactivated olefins with primary aliphatic amines based on the combination of a palladium catalyst, a bidentate … WebAcylation with enamines Direct acylation of ketones with esters using ethoxide only works well with reactive nonenolisable acylating agents This is because they can’t be deprotonated and react with themselves (Claisen condensation) instead of with the ketone. Another problem is that ketones are a bit more reactive than esters, and tend to …
