The present application relates to mixed Mg/Li amides of the general formula
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R 1 R 2 N-MgX·zLiY€ƒ€ƒ€ƒ€ƒ€ƒ(I),
wherein
R 1 , R 2 and R 3 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 R 1 and R 2 only, the silyl derivatives thereof; one of R 1 and R 2 may be H; or R 1 and R 2 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. |
