FACILE SYNTHESIS OF ARYL CYANIDES FROM IODIDES CATALYZED BY PALLADIUM TRIPHENYLPHOSPHINE COMPLEX

Abstract Cyanogenation of iodobenzene with potassium cyanide has been found to proceed smoothly in tetrahydrofuran in the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium(O). The reaction involves an intermediate, iodo(phenyl)bis(triphenylphosphine)palladium(II), which acts as a retracing species in the catalytic reaction path.
