Abstract
The invention relates to a process for the production of an organometallic compound according to formula (1): MALjYrX(p.(n+v+r)Rn (formula 1) where: M is a metal of groups 3-13 or the lanthanide series, and p is the valency of the metal M, A represents an anionic spectator ligand whose valency v is 1 or 2, Y is a spectator ligand represented by formula (2): wherein the spectator ligand is covalently bonded to the metal M via the imine nitrogen atom, Sub1 is a substituent, which comprises a group 14 atom through which SUb1 is bonded to the imine carbon atom, Sub2 is a substituent, which comprises an atom of groups 15-16, through which Sub2 is bonded to the imine carbon atom, sub1 and sub2 might be connected to each other forming a ring system, r is an integer>0, L is an optional neutral Lewis basic ligand, j is an integer denoting the number of neutral ligands L, X is an halide, and R is an anionic ligand, wherein an organometallic reagent according to formula (3), MALjXp−v (formula 3), is contacted with an alkylating agent, thus forming a precursor in which at least one of the halide atoms is replaced by an anionic ligand R that may be independently selected from the group consisti…
