This method is advantageous in respect of energy and process. Specifically, an oxidation product of a cycloalkane is obtained by oxidizing the cycloalkane in a liquid-liquid two phase system using an aqueous solvent in the presence of a nitrogen atom-containing cyclic compound which contains, as its ring constituent, a structure represented by following Formula (I): wherein X represents an oxygen atom or an —OR group, and wherein R represents a hydrogen atom or a hydroxyl-protecting group, and which has a solubility in water at 25° C. of 0.5 g/100 g-H2O or more.

  • Publication number: 20090326235
    Abstract: 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.
