Abstract
The present invention relates to anhydrous solutions of MXLiA in a solvent, wherein M is a lanthanide including lanthanum, or yttrium or indium; z>0; and X and A are independently or both monovalent anions, preferably Cl, Br or I. The solution is readily prepared by dissolving or suspending MXor its hydrate and z equiv LiA in water or hydrophilic solvents, or mixtures thereof, removing the solvent under vacuum and dissolving the resulting powder in another solvent. The solution of MXLiA can advantageously be used e.g. in addition reactions of Grignard reagents to ketones and imines. Even the catalytic use of MXLiA is possible.
