    摘要： A process for producing a transition metal complex of formula (B) wherein M is Fe[II], Fe[III], Co[I], Co[II], Co[III], Mn[l], Mn[II], Mn[III], Mn(IV], Ru[II], Ru[III] or Ru[IV]; X represents an atom or group covalently or ionically bonded to the transition metal M; T is the oxidation state of the transition metal M and b is the valency of the atom or group X; R1, R2, R3, R4, R5, R6 and R7 are independently selected from hydrogen, halogen, hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl; and when any two or more of R1-R7 are hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl, the two or more can be linked to form one or more cyclic substituents; comprising reacting together in a single stage reaction components comprising (1) precursors capable of forming Ligand (B) and (2) a compound of the formula M[T]-(T/b)X. The complex can be used as a catalyst for the polymerisation of 1-olefins.
