1D ~1H and ~13C, and 2D ~1H NOESY NMR were used to established that cyanoacetylhydrazones of aliphatic and aromatic aldehydes and ketones in CDCl_3 and (CD_3)_2SO solutions have a linear structure, exist as a mixture of geometric isomers by the C=N bond, and exhibit hindered amide ...

Hydrazones derived from 3-sulfanylpropionic acid hydrazide and aromatic aldehydes and ketones have mostly linear structures of different stereoisomers arising from Z-E isomerism with respect to the double C=N bond and restricted rotation about the C(O)-N bond. Condensation products of 3-sulfanyl...
studies of a series of twelve 1,2-dithiole-3-ylidene ketones and aldehydes have shown that the geometry of the carbon backbone is the same as found in 1,6,6aλ4-trithiapentalenes. No evidence has been found which favours a bicyclic structure for the system. A linear correlation of ...

The formation of an imine is an important reaction. Usually, primary amines tend to react with ketones and aldehydes to produce imines. When we take formaldehyde (R′ = H), the products generally exist as cyclic trimers. RNH2 + R′2C=O → R′2C=NR + H2O When these imines go thro...
The amino and carbonyl groups in the urea molecule exhibit high reactivity. The amino groups can participate in chemical reactions such as acid-base reactions, while the carbonyl group is involved in reactions with aldehydes, ketones, and other compounds. These reactive groups make urea widely utili...
