Abstract: A macromolecules containing a metal and a use thereof as a catalyst are disclosed. The macromolecules containing a metal may be obtained by causing a ligand to react with a zinc compound or a cobalt compound. The ligand has an imidazole group that is bonded to a macromolecule via a linker. The metal-containing macromolecules are highly active as a catalyst, stable, and easy to recover and reuse.

Abstract: The invention relates to a use of a fluorination gas, and the elemental fluorine (F2) is present in a high concentration, for example, in a concentration of elemental fluorine (F2), especially of equal to much higher than 15 or even 20% by volume, and to a process for the manufacture of a fluorinated compound by direct fluorination employing a fluorination gas, wherein the elemental fluorine (F2) is present in a high concentration. The process of the invention is directed to the manufacture of a fluorinated compound, for the exception of fluorinated benzene, by direct fluorination. Especially the invention is of interest in the preparation of fluorinated organic compounds, final products and as well intermediates, for usage in agro-, pharma-, electronics-, catalyst, solvent and other functional chemical applications. The fluorination process of the invention may be performed batch-wise or in a continuous manner.

Abstract: The present invention provides a process for purifying a monoterpene or sesquiterpene having a purity greater than about 98.5% (w/w). The process comprises the steps of derivatizing the monoterpene (or sesquiterpene) to produce a monoterpene (or sesquiterpene) derivative, separating the monoterpene (or sesquiterpene) derivative, and releasing the monoterpene (or sesquiterpene) from the derivative. Also encompassed by the scope of the present invention is a pharmaceutical composition comprising a monoterpene (or sesquiterpene) having a purity greater than about 98.5% (w/w). The purified monoterpene can be used to treat a disease such as cancer. The present monoterpene (or sesquiterpene) may be administered alone, or may be co-administered with radiation or other therapeutic agents, such as chemotherapeutic agents.

Abstract: A method of preparing a difluorinated alcohol compound is provided. The difluorinated alcohol compound can be easily synthesized when an aldehyde and N-fluorobenzenesulfonimide are reacted in the presence of L-proline, and thus the method has advantage in that preparation processes are simple and reagents are economical and safe, compared to the related-art methods. Therefore, the preparation method can be effectively applied to prepare a difluorinated alcohol used in various applications for raw materials such as functional medicines, agricultural chemicals, polymerizable compounds, etc.
