Hasegawa, Minoru published the artcileSynthesis and properties of antimony compounds of the type Sb(OSiR3)3, Product Details of C9H22OSi, the publication is Nippon Kagaku Kaishi (1995), 550-6, database is CAplus.
Novel organoantimony compounds Sb(OSiR3)3 [1, R1 = R2 = R3 = Me; 2, R1 = R2 = R3 = Pr; 3, R1 = R2 = R3 = i-Pr;4, R1 = R2 = Me, R3 = t-Bu; 5, R1 = R2 = R3 = Ph] were prepared in 41-81% yields by the reaction of SbCl3 with NaOSiR3 (1:3 mol ratio) in toluene. These compounds were characterized by IR, 1H, 13C, and 29Si-NMR, and MS spectroscopy. According to MS and NMR spectral data, each compound appears to be a monomer. They are subject to hydrolysis at room temperature Thus, treatment of 1–4 with a large excess of H2O under slightly forced conditions gave the corresponding silanols and Sb trioxides. IR and XPD data suggest the resulting Sb trioxides are two polymorphs; the 1st polymorph is senarmontite obtained by hydrolysis of 1–4 in H2O/MeOH and the 2nd polymorph is valentinite given by hydrolysis of 3 and 4 in H2O/acetone.
