Copper-Mediated Cyanation of Aryl Halide with the Combined Cyanide Source.

A simple copper-mediated cyanation of aryl halide with the combination of ammonium bicarbonate and N,N-dimethylformamide as a cyanide source is achieved, providing nitriles in moderate to good yields. This new approach represents an exceedingly practical and safe method for the synthesis of aryl nitriles. [ABSTRACT FROM AUTHOR]
