Embodiments are directed to a metal-ligand complex catalyst precursor, (L1)(L2)X(R1)(R2), and methods for producing the same from a compound of formula Q2X(R1)(R2). L1 and L2 are independently -R3-Z1 or -R4-Z1. R1 and R2 are independently selected from a hydrogen atom, (C1-C40)hydrocarbyl and, optionally, R1 and R2 are connected to form a ring having from 3 to 50 atoms in the ring, excluding hydrogen atoms. X is Si, Ge, Sn, or Pb. Each Q is independently Ar1-Y1R3- or Ar2-Y2-R4-. R3 and R4 are independently selected from -(CRC 2)m-, where m is 1 or 2, and where each Rc is independently selected from the group consisting of (C1-C40)hydrocarbyl, (C1-C40)heterohydrocarbyl, and -H. Y1 and Y2 are independently S, Se, or Te. Ar1 and Ar2 are independently (C6-C50)aryl. Ar1-Y1-R3- and Ar2-Y2-R4- are not identical. Each Z1 is independently selected from Cl, Br, and I.
本实施例涉及一种金属配体复合物催化剂前体(L1)(L2)X(R1)(R2),以及从式Q2X(R1)(R2)化合物制备上述催化剂前体的方法。其中,L1和L2独立地为-R3-Z1或-R4-Z1。R1和R2独立地选自氢原子、(C1-C40)烃基和/或R1和R2连接形成具有3至50个原子的环,不包括氢原子。X为Si、Ge、Sn或Pb。每个Q独立地为Ar1-Y1R3-或Ar2-Y2-R4-。R3和R4独立地选自-(CRC2)m-,其中m为1或2,每个Rc独立地选自由(C1-C40)烃基、(C1-C40)杂烃基和-H组成的群。Y1和Y2独立地为S、Se或Te。Ar1和Ar2独立地为(C6-C50)芳基。Ar1-Y1-R3-和Ar2-Y2-R4-不相同。每个Z1独立地选自Cl、Br和I。
