Method for producing amido-zinc halide/alkali- metal halide compounds

A method for preparing a compound of formula

• R1R2N—ZnY*LiY (I)
• comprising the steps of
• a) dissolving a primary or secondary amine in an aprotic organic solvent,
• b) metering a lithium base (RxLi) into the solvent containing the primary or the secondary amine to form a lithium-containing mixture, and
• c) adding ZnY2 to the lithium-containing mixture;
• wherein R1 and R2 are independently selected from H, substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, a linear, branched, or cyclic substituted or unsubstituted alkyl, alkenyl, alkynyl, or the silyl derivatives thereof;
• wherein R1 and R2 may together form a cyclic or polymeric structure in which at least one of the radicals R1 and R2 is not H;
• Y is selected from the group consisting F;
• Cl;
• Br;
• I;
• CN;
• SCN;
• NCO;
• HalOz, where z is 3 or 4 and Hal is selected from Cl, Br, and I;
• NO3;
• BF4;
• PF6;
• H;
• a carboxylate of the general formula RxCO2;
• an alcoholate of the general formula ORx;
• a thiolate of the general formula SRx;
• R13(O)O2;
• or SCORx;
• or SCSRx;
• OmSRx, where m is 2 or 3;
• or NOR, where n is 2 or 3;
• and derivatives thereof;
• where Rx is a substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, a linear, branched, or cyclic substituted or unsubstituted alkyl, alkenyl, alkynyl, or the derivatives thereof, or H.
