    Abstract: Process for preparing cyclometallated transition metal-carbene complexes comprising at least one carbene ligand, which comprises reacting a ligand precursor with a base, an auxiliary reagent and a metal complex comprising at least one metal M1 (route A) or reacting the ligand precursor with a basic auxiliary reagent and a metal complex comprising at least one metal M1 (route B). The present invention further relates to the use of an auxiliary reagent selected from among salts comprising at least one metal selected from the group consisting of Ag, Hg, Sb, Mg, B and Al together with a base in a process for preparing cyclometallated metal complexes.

    Abstract: The present invention relates to 2,6-bis(aminomethyl)piperidine derivatives as such (in the following text abbreviated to “2,6-BAMP derivatives”) which are defined by the general formula (I) shown in the following text. In addition, the present invention relates to a process for preparing such 2,6-BAMP derivatives by hydrogenation of the corresponding 2,6-dicyanopiperidine derivatives (hereinafter abbreviated to “2,6-DCP derivatives”) in the presence of a catalyst. The present invention further provides for the use of the 2,6-BAMP derivatives of the invention as hardeners for epoxy resins, as intermediate in the preparation of diisocyanates, which play an important role in the production of polyurethanes, as starters in the preparation of polyetherols and/or as monomers for polyamide production. The present invention further relates to the diisocyanates as such prepared from the 2,6-BAMP derivatives and also the corresponding preparative process.
