KBrO3/MoO3: An efficient reagent system for the oxidative deprotection of semicarbazones, 1,1-diacetates and acetals

Semicarbazones, 1,1-diacetates and acetals are efficiently converted to their corresponding carbonyl compounds using synergistic effect between KBrO3 and MoO3 in refluxing CH3CN–H2O in good to high yields.
