Abstract

An Ag ₄ diamond is encapsulated by silicotungstate ligands in TBA ₈[Ag ₄(DMSO) ₂(γ-H ₂SiW ₁₀O ₃₆) ₂]·2 DMSO·2 H ₂O (Ag4; DMSO=dimethyl sulfoxide, TBA=tetra-n-butylammonium), which was obtained by reaction of TBA ₄H ₄[γ-SiW ₁₀O ₃₆] with AgOAc in an organic medium. Polyoxometalate Ag4 (see picture) selectively catalyzes hydrolytic oxidation of various silanes to the corresponding silanols in high yields (72-96 %).
