Reaction of aliphatic ketone semicarbazone, such as acetone semicarbazone (VIIe), methylethylketone semicarbazone (VIIf), and cyclohexanone semicarbazone (VIIg), did not afford the VIII-type... work-up make this method a novel and useful one relative to the present meth- odologies for regeneration of carbonyl compounds from their derivatives under microwave irradiation.
Identification of an unknown carbonyl
The reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases, (compounds having a C=N function). This reaction plays an important role in the synthesis of 2º-amines, as discussed earlier .... Cyclohexanone semicarbazone is reported to melt at 166 o C; furfural semicarbazone at 202 o C (ii) Competitive Semicarbazone Formation Prepare a homogeneous solution of cyclohexanone (0.05 mole, 4.9 g) in furfural (0.05 mole, 4.9 g, freshly distilled) and divide it into two parts in the ratio 2:1.
