    Abstract: The invention concerns processes for the synthesis of a compound of the formula: wherein: R1 and R2 are each, independently, C1-C12 alkyl, CO2R3, OR4, R5(OR6), or C6-C18 aiyl; R3 -R6 are each, independently, C1-C12 alkyl or C6-C12 aryl; and n and m are each, independently, O or an integer from 1-5; said process comprising: - contacting a compound of the formula H0-R7-0H with BH3 and a compound of the formula in the presence of a nickel-containing catalyst to produce a first product, where R7 is a C2-C12 hydrocarbon group and X is a halogen, OMs or OTs; - contacting the first product in situ with a compound of the formula: in the presence of a nickel-containing catalyst to produce a compound of formula I, where Z is a halogen.

    Abstract translation: 本发明涉及合成下式化合物的方法:其中:R 1和R 2各自独立地为C 1 -C 12烷基,CO 2 R 3,OR 4,R 5(OR 6)或C 6 -C 18芳基; R 3 -R 6各自独立地为C 1 -C 12烷基或C 6 -C 12芳基; 且n和m各自独立地为O或1-5的整数; 所述方法包括:在含镍催化剂存在下使式HO-R7-H的化合物与BH 3和下式化合物接触以产生第一产物,其中R 7是C 2 -C 12烃基,X 是卤素,OM或OT; - 将第一产物原位与下式化合物接触:在含镍催化剂存在下制备其中Z为卤素的式I化合物。
