Tris(cyclohexyl)hydroxoantimony(V) compounds, (C6H11)3Sb(OH)Y, Y=Cl, Br, CH3COO, and NO3, were prepared by the hydrolysis of μ-oxo-bis, <(C6H11)3SbX>2O, in a mixed solvent of acetone and water(7:3) or by a reaction of silver salts with <(C6H11)3SbX>2O in the same solvent.When Y=Cl and Br, the dehydration of the hydroxo compounds, giving the μ-oxo compounds, <(C6H11)3SbY>2O, occurred readily.However, when Y=CH3COO and NO3, the hydroxo form is stable.In the IR spectra of these hydroxo compounds in dichloromethane solution, the ν(O-H) band was observed at ca. 3630 cm^-1 and the ν(SbO) band, at 565-513 cm^-1.The hydrolysis of several μ-oxo compounds, 2O, R=CH3, C2H5, i-C3H7, C6H5, and p-CH3C6H4, Y=Cl, Br, CH3COO, and NO3, in a water-saturated dichloromethane solution was studied by using the IR spectra.All the compounds were hydolyzed in this solvent, but only the starting μ-oxo compounds were recovered from this solution.
