<p>The present application relates to mixed Mg/Li amides of the general formula R1R2N-Mg(NR3R4)mX,.m zLiY (II) wherein R<SUP>1</SUP>, R<SUP>2</SUP>, R<SUP>3</SUP>, and R<SUP>4</SUP> are, independently, selected from H, substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, linear, branched or cyclic, substituted or unsubstituted alkyl, alkenyl, alkynyl, or silyl derivatives thereof; and R<SUP>1</SUP> and R<SUP>2</SUP> together, or R<SUP>3</SUP> and R<SUP>4</SUP> together can be part of a cyclic or polymeric structure; and wherein at least one of R<SUP>1</SUP> and R<SUP>2</SUP> and at least one of R<SUP>3</SUP> and R is other than H; X and Y are, independently, selected from the group consisting of F; Cl; Br; I; CN; SCN; NCO; HaIO<SUB>n</SUB> , wherein n = 3 or 4 and Hal is selected from Cl, Br and I; NO<SUB>3</SUB>; BF<SUB>4</SUB>; PF<SUB>6</SUB>; H; a carboxylate of the general formula R<SUP>X</SUP>CO<SUB>2</SUB>; an alcoholate of the general formula ORX; a thiolate of the general formula SR<SUP>X</SUP>; R<SUP>X</SUP>P(O)O<SUB>2</SUB>; or SCOR<SUP>X</SUP>; or SCSR<SUP>X</SUP>; O<SUB>n</SUB>SR<SUP>x</SUP>, wherein n = 2 or 3; or NO<SUB>n</SUB>, wherein n = 2 or 3; and a derivative thereof; wherein R<SUP>x</SUP> is a substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, linear, branched or cyclic, substituted or unsubstituted alkyl, alkenyl, alkynyl, or derivatives thereof, or H; m is O or 1 ; and z > O; as well as a process for the preparation of the mixed Mg/Li amides and the use of these amides, e.g. as bases.</p> |
