Abstract

Thiosemicarbazones of cyclic aldehydes are prepared by reacting a thiosemicarbazone of a ketone with a cyclic aldehyde. In examples: (1) the thiosemicarbazone of benzaldehyde-4-carboxylic acid is obtained by dissolving acetone-thiosemicarbazone in acetic acid and heating with benzaldehyde-4-carboxylic acid in methanol; and (2) 4-acetaminobenzal-thiosemicarbazone is obtained from cyclohexanonethiosemicarbazone and 4-acetaminobenzaldehyde. Other cyclic aldehydes specified are m - nitrobenzaldehyde, p - ethylsulphone - benzaldehyde and 2 - chloro - 5 - nitrobenzaldehyde. Specification 670,401 is referred to.
