The invention relates to a process for the production of a metal-organic compound according formula 1: MAL j �¢ Y r �¢ X p - ( n + v + r �¢ R n
where:
M is a metal of group 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 an spectator ligand represented by formula 2:
wherein the spectator ligand is covalently bonded to the metal M via the imine nitrogen atom, Sub 1 is a substituent, which comprises a group 14 atom through which Sub 1 is bonded to the imine carbon atom, Sub 2 is a substituent, which comprises an atom of group 15-16, through which Sub 2 is bonded to the imine carbon atom, sub1 and sub 2 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 a metal-organic reagent according to formula 3, MAL j �¢ X p - v
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 consisting of alkyl, arylalkyl, aryl, or a combination thereof, which precursor is subsequently contacted with an imine according to formula 2.
