1. Process for preparing an alkaline earth metal-complexed metal bisamide of formula (I) and/or a tautomer thereof where AE is an alkaline earth metal selected from calcium and magnesium; M is a metal selected from metals from groups 3, 4, 7, 8, 9, 10, 11, 12, 13 of the Periodic Table of the Elements and the group of the lanthanoids; X is a halogen atom selected from the group consisting of fluorine, chlorine, bromine and iodine; R1 and R2 are each independently selected from the group consisting of (C1-C8)alkyl optionally substituted by 1-2 R3 radicals; R3 is independently selected from halogen, (C1-C3)alkoxy, (C1-C3)haloalkoxy and (C2-C4)dialkylamino; or R1 and R2 together form a —(CH2)4—, —(CH2)5— or —(CH2)2O(CH2)2— group, where each of these groups may optionally be substituted by 1-4 R4 radicals; R4 is selected from halogen, (C1-C3)alkyl, (C1-C3)alkoxy, (C1-C3)haloalkoxy and (C2-C4)dialkylamino or (C2-C4)alkoxycarbonyl, by reacting a chloroamine of formula (II) in which the R1 and R2 radicals are each as defined above with (i) metallic magnesium and/or calcium and/or (ii) a magnesium and/or calcium halide and (iii) an amount of a metal halide (Mn+X−n) and/or (iv) an amount of a metal (M), where M and X are each as defined above. |
