A facile and convenient method for deprotection of thiocarbonyls to their carbonyl compounds using oxone under aprotic and nonaqueous conditions

Abstract

The reaction of oxone as an inexpensive, stable, and commercially available reagent with thiocarbonyl compounds in refluxing acetonitrile has been studied. Primary, secondary, and tertiary thioamides and thioureas are converted to their oxo analogues efficiently. Thiono esters also are transformed to their corresponding esters, while thioketones remained intact under these conditions.
