Abstract: A palladium-catalyzed cyanation of aryl dimethylsulfonium salts using cheap, nontoxic, and bench-stable K4[Fe(CN)6]·3H2O as the cyanating reagent has been developed. The reactions proceeded well under base-free conditions with various sulfonium salts and provided aryl nitrile… read more here.

DOI: 10.1246/cl.170798
Abstract: The copper-catalyzed cyanation of aryl iodides is described using nitromethane as a CN source. In situ generation of a “CN” species from nitromethane is plausible. This strategy is an advantageous synthetic method for the construction… read more here.
