摘要: Abstract The attack of electrophilic reagents on the azomethine-carbon hydrazones has been explained by their aza-analogous enamine-structure. According to this interpretation substitution enamines with isocyanates employed successfully benzaldehyde-N,N-tetramethylenehydrazones II. These react sulfonylisocyanates IV, give phenylglyoxylic-acid-arylsulfonylamide-N,N-tetramethylenehydrazones V. structure compounds V determined physical and chemical methods.
