Abstract A series of thioamides, thioureas and thioesters are transformed to their corresponding carbonyl compounds in good to excellent yields with oxone under solid phase conditions, while thioketones remained unchanged under these conditions.
Efficient and Convenient Deprotection of Thiocarbonyl to Carbonyl Compounds Using 3-Carboxypyridinium and 2,2'-Bipyridinium Chlorochromates in Solution, Dry Media, and under Microwave Irradiation
deprotection reactions is reported. Different types of thioamides, thioureas, thiono esters, and thioketones are deprotected to their corresponding carbonyl compounds with these reagents in good to excellent yields. The reactions were carried out in solution, under solvent-free conditions, and under microwave irradiation. The results show that with both reagents the rates of the reactions and the yields

spectra. The vibrational bands revealed that both the Mn(II) and Fe(III) complexes are ketonic in nature, whereas the Fe(II) complex is an enolic one. The electronic absorption bands show that the metal ions are hexacoordinated to the ligand molecules. The thermogravimetric and differential thermogravimetric curves of the complexes showed several thermal decomposition steps ending with Fe 4 N, and Fe 10 N

A variety of thioamides and thioureas are rapidly transformed to their oxoderivatives with Bi(NO3)3·5H2O in excellent yields. However, thiono esters and thioketones are converted to their corresponding carbonyl compounds in only poor yields. Bi(NO3)3·5H2O is relatively non-toxic, insensitive to air and inexpensive. These features coupled with the selective deprotection of thioamides and thioureas
