(I)
wherein R
1
and R
2
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 R
1
and R
2
can form together a ring structure, or R
1
and/or R

can be part of a polymer structure; X
1
2
is a divalent anion or two monovalent anions that are independent from each other; X
2
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.
本发明涉及一般式(I)(R1R2N)2—Zn.aMgX12.bLiX2的
锌酰胺碱,其中R1和R2均独立地选择其取代或未取代的线性或支链烷基,烯基,炔基或其
硅基衍
生物,以及取代或未取代的芳基或杂环芳基,其中R1和R2可以一起形成环状结构,或者R1和/或R2可以是聚合物结构的一部分;X12是二价阴离子或两个彼此独立的单价阴离子;X2是单价阴离子;a>0;b>0。
锌酰胺碱可以用于芳香族物质的去质子化和
金属化等方面。
