1. A PROCESS FOR THE SELECTIVE ISOMERIZATION OF A TERMINALLY CONJUGATED POLYENE HAVING A CARBON CHAIN OF AT LEAST SIX CARBON ATOMS, WHEREBY TERMINAL CONJUGATED UN SATURATION IS SHIFTED TO AN INTERNAL POSITION, THE PROCESS COMPRISING CONTACTING THE POLYENE WITH A CATALYST CONSISTING ESSENTIALLY OF A HYDROGEN-EXPOSED MIXTURE OF (A) A COBALT (II) SALT, (B) AT LEAST ONE OF GROUP IA CYANIDE AND A GROUP IIA CYANIDE, WITH THE PROVISO THAT THE RATIO OF CYANIDE ION GRAM-EQUIVALENTS TO COBALT GRAM-ATOMS IS AT LEAST 3 TO 1; THE PROCESS BEING CARRIED OUT IN THE PRESENCE OF A SOLVENT CONTAINING 0-10% WATER AND AT A TEMPERATURE OF ABOUT 25-150* C.
