Bamboo Salt Effects on Hydrolysis of Estertin(IV) Complex

摘要

In Korea, bamboo salt has been sometimes ingested as supplementary health-food and remedy since it has been known to exhibit various therapeutic effects on inflammation, viral disease, diabetes, circulation disorders and cancer, even though its effects are not completely understood. Actually, it has been used as additives for face cream, tooth paste, cosmetics, food additives, cleaning materials, and antibacteria. Thus, both food and pharmaceutical scientists are interested in research of bamboo salt in order to illuminate its either therapeutics or effects. Bamboo salt has been known to contain various trace ions and to exhibit basic pH. However, to date, its task-specific application to pure chemistry remains unexplored. On the other hand, the chemistry of 'estertin(IV) chlorides' has attracted considerable attention because of a PVC stabilizer with low mammalian toxicities and interesting coordination chemistry since Akzo chemists discovered a convenient synthetic route.13 Earlier systematic investigations on the estertin(IV) chlorides suggest that their chemistry and bonding modes are very sensitive to environment. Thus, this paper reports a preliminary result on the bamboo salt effects on the hydrolysis of 3-methoxy-3-oxopropyltin(IV) trichloride, [CH3OOCCH2CH2SnCl3] that shows a penta-coordinated Sn(IV) geometry with the intramolecular carbonyl oxygen-to-tin coordination.
