摘要

A divanadium-substituted phosphotungstate TBA4 [γ-PW10O38V2 (μ-OH)(μ-O)](I, TBA= tetra- n-butylammonium) reacts with one equivalent H+ to form a bis-μ-hydroxo species [γ- PW10O38V2 (μ-OH) 2] 3−(I′) in organic media. The strong electrophilic oxidants such as [γ- PW10O38V2 (μ-OH)(μ-OOH)] 3−(II) and [γ-PW10O38V2 (μ-η2: η2-O2)] 3−(III) are formed by the reaction of the bis-μ-hydroxo species with H2O2. In the presence of I and H+, H2O2- ...
