Abstract

The present invention relates to zinc amide bases of the general formula (I)(R1R2N)2—Zn.aMgX12.bLiX2 (I)wherein R1 and R2 are each independently selected from substituted or unsubstituted, linear or branched alkyl, alkenyl, alkynyl or silyl derivatives thereof, and substituted or unsubstituted aryl or heteroaryl, and wherein R1 and R2 can form together a ring structure, or R1 and/or R2 can be part of a polymer structure; X12 is a divalent anion or two monovalent anions that are independent from each other; X2 is a monovalent anion; a is >0; and b is >0. The zinc amide bases can be used, amongst other things, for deprotonation and metallization of aromatics.
