Procedure for preparing organometallic compounds of general formula: **(See formula)** in which M is a Group IV transition metal, R1-5 are substituents that may be the same or different, n is an integer between 0 and 3, provided that when M is titanium R1-5 are at least some different to hydrogen, L is an anionic ligand, L'is a neutral ligand and m is an integer between 0 and 2, characterized in that it comprises reacting an organometallic compound of an element of Groups I and III that contains at least one ligand of the general formula **(See formula)** wherein R1-5 are defined as above with a Group IV transition metal tetrahalide.
