Reaction Conditions:

with perchloric acid;TBA₄[γ-HPV₂W₁₀O₄₀];dihydrogen peroxide in water;acetonitrile;tert-butyl alcohol at 24.84; for 0.5 h;chemoselective reaction;

Steps:

General procedure: TBA₄[γ-HPV₂W₁₀O₄₀](TBA = [(n-C4H9)4N]+, 1 mol), 70% aqueous perchloric acid (1 mol), 1a (1 mmol), and CH3CN/t-BuOH (1.5/1.5 mL) were charged in a reaction vessel. The reaction was initiated by addition of 30% aqueous H₂O₂ (1 mmol), and the reaction solution was periodically analyzed. Before the GC analysis,the remaining H2O2 was decomposed at 273 K by addition of Ru(OH)_x/Al₂O₃
