Patent number: 8470982Abstract: The present invention relates to anhydrous solutions of MX3-Z LiA 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 MX3 or 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 MX3-Z LiA can advantageously be used e.g. in addition reactions of Grignard reagents to ketones and imines. Even the catalytic use of MX3-Z LiA is possible.Type: GrantFiled: September 1, 2006Date of Patent: June 25, 2013Assignee: Ludwig-Maximilians-UniversitaetInventors: Paul Knochel, Arkady Krasovskiy, Felix Kopp
