Yield:951-02-0 97%

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
