Abstract
Of the thiosemicarbazones of benzaldehyde with substituent in the para position which were said to be as effective as Tibione, p-ethylsulfonylbenzaldehyde thiosemicarbazone was prepared by the condensation of thiosemicarbazide and ethylsulfonylbenzaldehyde. This aldehyde was obtained from the corresponding methyl derivative, i.e. p-tolylethyl sulfone, by its oxidation with chromic and sulfuric acids in acetic anhydride to aldehyde diacetate, followed by hydrolysis.
