title: Sterically controlled esterification on Bis(mu-hydroxo) dioxovanadium site in gamma-H2SiV2W10O40(4-).
abstract: 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.
