This research aims to develop a palladium-catalyzed method for synthesizing ketones through the coupling of carboxylic acids and aryl bromides.
Utilized palladium catalyst and cyanuric chloride for dehydroxylation at room temperature in THF.
Employed 4-methylmorpholine, magnesium turnings, and lithium chloride to facilitate the reaction.
Conducted scaled-up syntheses and postmodification on bioactive molecules.
Successfully accessed various unsymmetrical ketones with modest to good yields.
Demonstrated good functional group tolerance in the cross-coupling reactions.
Identified triazine-based triester and aryl magnesium reagent as key intermediates in the reaction mechanism.
