An extensive range of functionalized aliphatic ketones with good functional‐group tolerance has been prepared by a NiI‐promoted coupling of either primary or secondary alkyl iodides with NN2 pincer NiII‐acyl complexes. The latter were easily accessed from the corresponding NiII‐alkyl complexes with stoichiometric CO. This Ni‐mediated carbonylative coupling is adaptable to late‐stage carbon isotope...
An efficient Pd‐catalyzed carbonylative α‐arylation of 2‐oxindoles with aryl and heteroaryl bromides for the one‐step synthesis of 3‐acyl‐2‐oxindoles has been developed. This reaction proceeds efficiently under mild conditions and is complementary to the more common oxindole forming reactions. The transformation only requires a mild base and provides good to excellent yields even with heteroaromatic...
