The present invention relates to a process for the preparation of a compound of formula (I), wherein X is -CH2-, -CH2-CH2-, -CH2-CH2-CH2- or -CH2-CH2-CH2-CH2-; Y1 is -CH2-; -CH2-CH2- or -NH-; Y2 is NHR7 or SH; wherein R7 is hydrogen, C1-C4alkyl or phenyl; R-1 and R2, independently from each other, represent aliphatic or aromatic groups; R3 and R4, independently from each other, represent aliphatic or aromatic groups; R5 and R6 are each hydrogen or represent together with the carbon atoms to which they are bonded, a phenyl ring; which process comprises reacting a compound of formula II [RuCI2(R8)n]m (II), wherein n is 1 and m is > 1 which represents a polymeric structure if R8 is a molecule containing two alkene or alkyne moieties coordinating in an hapto-2 coordination mode to the metal; or n is 4 and m is 1 if R8 is a nitrogen, oxygen or sulfur containing molecule in which said nitrogen, oxygen or sulfur coordinate to the metal; in the presence of an inert solvent which boiling point is from 1 12°C to 165°C with a compound of formula (III), wherein R5, R6, Y1 and Y2 are as defined under formula I, and a phosphane of formula IV R3R4P-X-PR1 R2 (iv), wherein R1, R2, R3, R4 and X are as defined under formula I.
本发明涉及一种制备式(I)化合物的方法,其中X为-CH2-,-CH2-CH2-,-CH2-CH2-CH2-或-CH2-CH2-CH2-CH2-;Y1为-CH2-,-CH2-CH2-或-NH-;Y2为NHR7或SH;其中R7为氢、C1-C4烷基或苯基;R-1和R2,各自独立地表示脂肪族或芳香族基团;R3和R4,各自独立地表示脂肪族或芳香族基团;R5和R6分别为氢或与它们所连接的碳原子一起表示苯环;该方法包括将式II [RuCI2(R8)n]m(II)的化合物与式III的化合物在惰性溶剂的存在下反应,其中R5,R6,Y1和Y2在式I下定义,并与式IV的膦化合物反应,其中R1,R2,R3,R4和X在式I下定义,其中n为1,m>1,如果R8是含有两个烯烃或炔烃官能团协同配位到金属的分子,则代表聚合结构;如果R8是氮、氧或硫含有分子,则n为4,m为1,其中所述的氮、氧或硫配位到金属上。
