| titleOfInvention | Method of manufacturing phosphine compound |
| abstract | A method of preparing a compound (I) of general formula (R3-C)2P-L1-X-L2-P-(C-R3)2, in which each R is independently a pendant, optionally substituted, organic group through which the group is linked to tertiary carbon atom C; L1, L2 are independently a linking group selected from an optionally substituted lower alkylene chain connecting the respective phosphorous atom to the group X and X is a bridging group comprising an optionally substituted aryl moiety to which the phosphorous atoms are linked on available adjacent carbon atoms comprises the steps of (i) reacting together a compound (II) of formula A-L1-X-L2-A, in which A is a halogen atom, with a metal M in a suitable solvent to form an intermediate compound (III) of formula A-M-L1-X-L2-M-A, (ii) reacting said intermediate compound (III) with a compound (IV) of formula (R3-C)2P-A1, where A1 is a halogen atom which may be the same as or different form A, to form said compound (I). The compound (I) may be useful to form a catalyst system for the carbonylation of olefins. |
