The present invention relates to compounds of formula (I) wherein each of X, Y, Z is independently selected from 0, S, NR1, CR2R3, N and CR4, and where optionally X-Y, Y-Z, Z-E1 and X-E2 each independently form part of a saturated or unsaturated ring system which may be substituted or unsubstituted; m is 0 or 1; M is a metal selected from Ti[III], Ti[IV], Fe[II], Fe[III], Co[I], Co[II], Co[III], Ni[II], Cr[III], Mn[II], Mn[III], Mn[IV], Ru[II], Ru[III], Ru[IV], Pd[II], V[II], V[III], V[IV], V[V], Cu[I], Cu[II], Rh[I], Rh[III], Mo[III], Mo[V], Re[I] and Re[II]; each of E1 and E2 is independently selected from O, S, NR5, N, P, PR6, where at least one of either E1 or E2 carries a formal negative charge; L2 is a one electron donor ligand; n is zero or an integer such that the compound has an overall charge of zero or +1; L1 is NR7RB, PR7RB, OR7, SR7, O, S or NR16, imidazolyl, pyridinyl, benzimidazolyl or quinolinyl; each of R1-8 and R16 is independently H or a hydrocarbyl group; Q is a linker group; and r is 0 or 1. Further aspects of the invention relate to catalyst compositions comprising compounds of formula (I), and their use in the polymerisation of olefinically unsaturated monomers.
本发明涉及具有以下结构的化合物(I):其中X、Y、Z中的每一个独立选择自0、S、NR1、CR2R3、N和CR4,其中可选地X-Y、Y-Z、Z-E1和X-E2中的每一个独立地形成饱和或不饱和环系统的一部分,该环系统可以被取代或未取代;m为0或1;M为从Ti[III]、Ti[IV]、Fe[II]、Fe[III]、Co[I]、Co[II]、Co[III]、Ni[II]、Cr[III]、Mn[II]、Mn[III]、Mn[IV]、Ru[II]、Ru[III]、Ru[IV]、Pd[II]、V[II]、V[III]、V[IV]、V[V]、Cu[I]、Cu[II]、Rh[I]、Rh[III]、Mo[III]、Mo[V]、Re[I]和Re[II]中选择的金属;E1和E2中的每一个独立选择自O、S、NR5、N、P、PR6,其中E1或E2中的至少一个带有正式负电荷;L2是一个单电子供体配体;n为零或整数,使得化合物的总电荷为零或+1;L1为NR7RB、PR7RB、OR7、SR7、O、S或NR16、咪唑基、吡啶基、苯并咪唑基或喹啉基;R1-8和R16中的每一个独立地为H或烃基;Q为连接基团;r为0或1。本发明的其他方面涉及包含化合物(I)的催化剂组合物,以及它们在烯烃不饱和单体的聚合中的使用。
