Palladium-Catalyzed Decarboxylative Arylation of Potassium Cyanoacetate: Synthesis of α-Diaryl Nitriles from Aryl Halides. — In most cases, potassium cy-anoacetate (I) produces higher yields than its sodium analogue (VIII). If phenol-derived electrophiles (IVc) and (IVd) are used, the base-sensitive triflate produces a good, whereas arylation with the tosylate fails. — (YEUNG, P. Y.; CHUNG, K. H.; KWONG*, F. Y.; Org.
