The esterification of a bis(mu-hydroxo) dioxovanadium site in divanadium-substituted silicotungstate, gamma-H(2)SiV(2)W(10)O(40)(4)(-), with alcohols is sterically controlled: The secondary and tertiary alcohol esters are hardly formed (equilibrium constant < 0.01), and a large equilibrium constant of 75 is observed for the reaction with methanol. |
