| abstract | 1491134 Hydroformylation E I DU PONT DE NEMOURS & CO 4 Feb 1975 4722/75 Heading C2C A process for hydroformylating a compound having at least one active ethylenic group with the provisos: (i) at least two hydrogen atoms are attached to the unsaturated carbon atoms of each active ethylenic group; (ii) the active ethylenic groups are not conjugated with other aliphatic unsaturation; (iii) halogen or hydroxyl, if present are removed by at least two carbon atoms from an active ethylenic group; (iv) internal active ethylenic groups have the cis configuration; and (v) the compound is free of amine groups; comprises contacting the compound with carbon monoxide and hydrogen at a pressure of 1 to 1000 atmospheres and at a temperature of 25‹ to 200‹ C. with a catalyst of the formula L n MH+X- wherein n is 2, 3 or 4, M is nickel, palladium or platinum, L is a trivalent organophosphorus ligand R 3 P where each R, which may be the same or different, is selected from lower alkyl, aryl of up to 12 carbon atoms, or aryloxy of up to 12 carbon atoms (aryl may be alkyl or halo substituted), and X is hexafluorophosphate, bisulphate, acetate, trifluoroacetate, hexafluoroantimonate, hexachloroantimonate, tetrafluoroborate, hexachlorostannate, benzenesulphonate, methanesulphonate or trifluoromethane sulphonate. |
