A method for producing R 1 R 2 N-ZnY*LiY wherein R 1, R 2 are independently selected from H, substituted or unsubstituted aryl or heteroaryl having one or more heteroatoms, linear, branched or cyclic substituted or unsubstituted alkyl, alkenyl, alkynyl or their silyl derivatives; wherein R 1 and R 2 together can be part of a cyclic or polymeric structure, wherein at least one of the radicals R 1 and R 2 is not H; Y is selected from the group with F; Cl; Br; I; CN; SCN; NCO; HalO z, where z is equal to 3 or 4 and Hal is selected from Cl, Br and I; NO 3; BF 4; PF 6; H; a carboxylate of the general formula R x CO 2; an alcoholate of the general formula OR x; a thiolate of the general formula SR x; R x P O 2; or SCOR x; or SCSR x; O m SR x, where m is equal to 2 or 3; or NO n, where n is equal to 2 or 3; and their derivatives; wherein R x is a substituted or unsubstituted aryl or is heteroaryl having one or more heteroatoms, linear, branched or cyclic substituted or unsubstituted alkyl, alkenyl, alkynyl or their derivatives or H, characterised in that a primary or secondary amine is presented dissolved in an aprotic organic solvent, a) wherein the amine is presented dissolved in the concentration range of 10 to 90% by weight, and b) ZnY 2 solution in an aprotic organic solvent and R x Li are simultaneously added in a metered manner, wherein it is to be heeded that the metering of the R x Li is started first and only after 5 - 10 mol% R x Li has been added is the metering of the ZnY 2 solution started, and R x Li and the ZnY 2 solution are metered in at different locations in the reaction solution during the metering phase. R 1, R 2 are independently selected from H, substituted or unsubstituted aryl or heteroaryl having one or more heteroatoms, linear, branched or cyclic substituted or unsubstituted alkyl, alkenyl, alkynyl or their silyl derivatives; wherein R 1 and R 2 together can be part of a cyclic or polymeric structure, wherein at least one of the radicals R 1 and R 2 is not H; Y is selected from the group with F; Cl; Br; I; CN; SCN; NCO; HalO z, where z is equal to 3 or 4 and Hal is selected from Cl, Br and I; NO 3; BF 4; PF 6; H; a carboxylate of the general formula R x CO 2; an alcoholate of the general formula OR x; a thiolate of the general formula SR x; R x P O 2; or SCOR x; or SCSR x; O m SR x, where m is equal to 2 or 3; or NO n, where n is equal to 2 or 3; and their derivatives; wherein R x is a substituted or unsubstituted aryl or is heteroaryl having one or more heteroatoms, linear, branched or cyclic substituted or unsubstituted alkyl, alkenyl, alkynyl or their derivatives or H, a primary or secondary amine is presented dissolved in an aprotic organic solvent, a) wherein the amine is presented dissolved in the concentration range of 10 to 90% by weight, and b) ZnY 2 solution in an aprotic organic solvent and R x Li are simultaneously added in a metered manner, wherein it is to be heeded that the metering of the R x Li is started first and only after 5 - 10 mol% R x Li has been added is the metering of the ZnY 2 solution started, and R x Li and the ZnY 2 solution are metered in at different locations in the reaction solution during the metering phase. a) wherein the amine is presented dissolved in the concentration range of 10 to 90% by weight, and b) ZnY 2 solution in an aprotic organic solvent and R x Li are simultaneously added in a metered manner, wherein it is to be heeded that the metering of the R x Li is started first and only after 5 - 10 mol% R x Li has been added is the metering of the ZnY 2 solution started, and R x Li and the ZnY 2 solution are metered in at different locations in the reaction solution during the metering phase.
