THE PROCESS FOR THE ADDITION OF (A) AN ALLYLIC HALIDE REACTANT CONTAINING ONE ETHYLENIC LINKAGE, FROM 1 TO 2 ALLYLIC HALOGEN ATOMS OF ATOMIC NUMBER FROM 17 TO 35 AND FROM 3 TO 20 CARBON ATOMS, SELECTED FROM HYDROCARBON ALLYLIC HALIDE REACTANTS AND HALOHYDROCARBON ALLYLIC HALIDE REACTANTS WHEREIN EACH HALOGEN IS HALOGEN OF ATOMIC NUMBER FROM 17 TO 35, (B) AND AN OLEFINIC COMPOUND HAVING FROM 2 TO 20 CARBON ATOMS AND FROM 1 TO 2 ETHYLENIC LINKAGES, SELECTED FROM HYDROCARBON OLEFIN AND HALOHYDROCARBON OLEFIN WHEREIN EACH HALOGEN, IS HALOGEN OF ATOMIC NUMBER FROM 17 TO 35, IN LIQUID-PHASE SOLUTION IN A CYANOALKANE SOLVENT, THE MOLAR RATIO OF SOLVENT TO LIMITING REACTANT BEING FROM ABOUT 1:1 TO ABOUT 20:1, AT A TEMPERATURE FROM ABOUT 75*C. TO ABOUT 200* C., IN THE PRESENCE OF A CATALYTIC AMOUNT OF FERROUS HALIDE AS CATALYST.
