    • A method of manufacturing a compound 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 phosphorus atom to the group X and X is a bridging group comprising an optionally substituted aryl moiety to which the phosphorus atoms are linked on available adjacent carbon atoms, comprises: i) reacting together a compound of formula H-L1-X-L2-H with an organometallic compound to form an intermediate compound of formula M-L1-X-L2-M, where M is an alkali metal atom; ii) reacting said intermediate compound with a compound of formula (R3-C)2P-A, where A is a halogen atom, to form said compound of general formula (R3-C)2P-L1-X-L2-P-(C-R3)2, M is preferably lithium, potassium or sodium and the intermediate compound may be isolated or not. The reaction (i) may advantageously be carried out in the presence of a complexing agent such as tetramethyethylenediamine.
    • 制备通式为(R3-C)2P-L1-X-L2-P-(C-R3)2的化合物的方法,其中每个R独立地为侧基,任选取代的有机基团,基团 与叔碳原子C连接; L 1,L 2独立地为选自将各个磷原子连接至基团X的任选取代的低级亚烷基链的连接基团,并且X为包含任选取代的芳基部分的桥连基团,其中磷原子在可用的相邻碳原子上与其连接, 包括:i)使式H-L1-X-L2-H的化合物与有机金属化合物一起反应以形成式M-L1-X-L2-M的中间体化合物,其中M为碱金属原子; ii)使所述中间体化合物与其中A为卤原子的式(R3-C)2P-A的化合物反应以形成所述通式(R3-C)2P-L1-X-L2-P-( C-R3)2时,M优选是锂,钾或钠,并且中间体化合物可以是分离的或不分离的。 反应(i)可以有利地在络合剂如四甲基乙二胺存在下进行。
