THE PROCESS FOR THE PRODUCTION OF A Y-HALONITRILE PRODUCT BY THE 1,2-ADDITION TO MONO- TO TRIHALOACETONITRILE TO THE ETHYLENE DOUBLE BOND TO AN OLEFINIC COMPOUND OF FFROM 2 TO 20 CARBON ATOMS, SAID OLEFINIC COMPOUND BEING AN OTHERWISE HYDROCARBON COMPOUND HAVING A SINGLE FUNCTIONAL GROUP SELECTED FROM CARBONYL, CARBOXY, CARBOALKOXY, OR CYANO WHEREIN THE NON-CARBON-CARBON UNSATURATION OF SAID FUNCTIONAL GROUP IS CONJGATED WITH SAID ETHYLENIC LINKAGE, THE ETHYLENIC LINKAGE BEING THE ONLY NONAROMATIC CARBON-CARBON UNSATURATIION OF THE OLEFINIC COMPOUND, IN LIQUID, PHASE SOLUTION IN IERT SOLVENT WHEREIN THE MOLAR RATIO FO SAID HALOACETONITRILE TO SAID OLEFINIC COMPOUND IS FROM ABOUT 5:1 TO ABOUT 1:5, AT A TEMPERATURE FROM ABOUT 50*C. TO ABOUT 200*C., IN THE PRESENCE OF FROM ABOUT 0.005 MOLE TO ABOUT 0.5 MOLE PER MOLE OF LIMITING REACTANT OF A COPPER SALT AS CATALYST.
