    摘要: The invention relates to a method for producing metal complexes of formula (2) [MaLxXn]Ym (2), where M is a metal from the group consisting of Mn(II), Mn(III), Mn(IV), Fe(II), Fe(III) or Fe(IV), X is a coordinating compound selected from mono-, bi- or tri-charged anions or neutral molecules which can coordinate to a metal in mono-, bi- or tri-dentate form, Y represents a non-coordinating counter-ion which ensures charge equalization of the complex, L represents a ligand of formula (1) or the protonized or de-protonized form thereof, and a, x, n, m, R, R1, R2, R3 and z have the meanings described in claim 1. Said method is characterized in that the reaction of one or more ligands of formula (1) with an iron salt or manganese salt is carried out in an acetone/water mixture in a temperature range from 0 to 50° C. and for this purpose a solution or a suspension of the one or more ligands of formula (1) in acetone is brought in contact with an aqueous metal salt solution of the iron salt or manganese salt in the temperature range in which the reaction takes place.

    摘要: The process for preparing a novel product, pure crystalline methyl 2-acryloylamino-2-methoxyacetate, involves reacting pure crystalline, anhydrous acrylamido-glycolic acid in an anhydrous medium with methanol in the presence of hydrogen chloride. This is subsequently neutralized with an alkali metal bicarbonate, and then the mineral salts are filtered off. Finally, pure crystalline methyl 2-acryloylamino-2-methoxyacetate is obtained by taking up the concentrated reaction medium in 1,1,1-trichloroethane under vacuum.
