| Research Abstract |
In this study, polyoxometalates with various silver cluster have been synthesized by the reaction of dilacunary polyoxometalate and silver sources. In the presence of silver-cluster-containing polyoxometalates, hydrolytic oxidation of various kinds of silanes selectively proceeded, giving the corresponding silanols in high yields. For the purpose of the development of metal-cluster-containing polyoxometalates, syntheses of novel lacunary polyoxometalates have been investigated. We can successfully developed the syntheses of various divalent metal salts of dilacunary polyoxometalates. Although the encapsulation and substitution of multicobalt into dilacunary polyoxometalates without isomerization have been considered to be difficult, by the reaction of a cobalt salt of dilacunary polyoxometalate and required components, di- and tetracobalt-containing polyoxometalates could be synthesized.
