Abstract
It was shown by the data from quantum-chemical calculations that the phenylhydrazones of certain unsymmetrical carbonyl compounds (methyl ethyl ketone, acetoacetic and levulinic acids) have the transoid conformation in relation to the N-N bond. The relation between the regioselectivity of the Fischer reaction and the structure of the calculated compounds is discussed.
