Abstract
3-Oxo-3-(hetero)arylpropanenitriles can be synthesized via a carbonylative palladium-catalyzed α-arylation of tert-butyl 2-cyanoacetates with (hetero)aryl bromides followed by an acid-mediated decarboxylation step. Through the combination of only a stoichiometric loading of carbon monoxide and mild basic reaction conditions for the deprotonation step, an excellent functional group tolerance was ensured.
