Carbonyl Regeneration from Semicarbazones, Tosylhydrazones, Phenylhydrazones, and 2,4-Dinitrophenylhydrazones by Clay-Supported Ferric Nitrate

Phenacylsulfonylacetic esters — source for thiadiazoles, triazoles and oxadiazoles

“…There were different methods in the literature for the deoximation of oxime group [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. We have adopted the deoximation reaction of 8-10 using mild oxidizing agent 2-iodoxybenzoic acid catalyzed by -cyclodextrin in water at room temperature.…”

Selective Method for the Conversion of Oximes to Their Corresponding Carbonyl Compounds under Microwave Irradiation by N‐Bromo‐N‐Phenyl‐Para‐Toluenesulfonamide

“…[1][2][3] These compounds are also useful protecting groups in organic syntheses 4 and have found extensive application in the isolation of carbonyl compounds. [5][6] Several methods based on reductive, hydrolytic, and oxidative reactions have been developed for the cleavage of oximes. [7][8][9] Owing to the considerable importance of such compounds there is still scope for newer methods as the existing oxidative methods suffer from disadvantages such as long reaction time, 10 formation of over oxidation products and difficulties in isolation of products.…”

Facile and mild deprotection of semicarbazones under solvent-free conditions with N,N,N',N'-tetrabromo-benzene-1,3-disulfonylamide

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] Extensive studies on the deprotection of these derivatives have been carried out using various catalysts.…”
