    Abstract: Process for producing nickel(0)-phosphorus ligand complexes containing at least one nickel(0) central atom and at least one phosphorus-containing ligand, by reacting a nickel(II) compound with a reducing agent in the presence of the ligand to give a reaction mixture, characterized in that, a) in the reaction the molar ratio of reducing agent:nickel(II) compound is 1:1 to 1000:1, calculated as molar ratio of redox equivalents, b) in the reaction the molar ratio of phosphorus-containing ligand:nickel(II) compound is at most 30:1, calculated as molar ratio of P atoms:Ni atoms, c) in the resultant reaction mixture the nickel(0) content is at most 1.3% by weight, and d) the resultant reaction mixture is extracted by adding at least one dinitrile and at least one hydrocarbon, at least two immiscible phases forming.

    Abstract: The invention relates to a method for producing triethylenetetramine that is substituted with at least one methyl group (Me-TETA or methyl-substituted TETA compounds). Me-TETA is produced by hydrogenating biscyanomethyl imidazolidine (BCMI) in the presence of a catalyst. The present invention further relates to methyl-substituted TETA compounds as such. The present invention further relates to the use of methyl-substituted TETA compounds as an educt or intermediate product in the production of, for example, coatings or adhesives.
