The present application relates to mixed Mg/Li amides of the general formula
R1R2N-MgX·zLiY (I),
wherein
R1, R2 and R3 independently are selected from substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, linear, branched or cyclic, substituted or unsubstituted alkyl, alkenyl, alkynyl, or derivatives thereof, and, for R1 and R2 only, the silyl derivatives thereof; one of R1 and R2 may be H; or R1 and R2 together can be part of a cyclic or polymeric structure;
X and Y independently are selected amongst others from the group consisting of F; Cl; Br; I; CN; SCN; NCO; and z > 0, as well as a process for the preparation of the mixed Mg/Li amides and the use of these amides, e.g. as bases.
本申请涉及一般式为R1R2N-MgX·zLiY(I)的混合Mg/Li胺,其中
R1、R2和R3独立地选择自含有一个或多个杂原子的取代或未取代芳基或杂芳基,线性、支链或环状,取代或未取代的烷基、烯基、炔基或其衍生物,以及仅对于R1和R2,其硅基衍生物;R1和R2中的一个可以是H;或者R1和R2可以共同构成环状或聚合结构的一部分;
X和Y独立地从F、Cl、Br、I、CN、SCN、NCO等组中选择,z > 0,以及混合Mg/Li胺的制备方法和这些胺的用途,例如作为碱。
