Abstract It was shown in a paper concerning the syn-
thesis of alkyl-A-aminovlnyl ketones and
published earlier. (Rzi'j@hiift 1 1955, 40057)
that the refraction index ?n) of freshly dis-
tilled substances rises rapidly to a constant
magnitude and a surmise about a tautomeric
conversion was expressed. Basing on measure-
ments of the molecular refraction (MR), on the

determination of MR exaltation and of dis-
persion, on infrared spectra and on the com-
parison of received results with data of
model compoundy it is shown in the present
work that the enaminoimic tautomerism
RCOCH-CHNH2:;@@RC(OH)= CHCH-Mi takes place
In case of alkyl- -aminovinyl ketones. The
tautomeric form 4form) of iiethyl-,S -amino-
vinyl ketone (I) and of isobutyl-,B-aminovinyl
ketone, to which the structure RC(OH) CHCH NH
had been ascribed o.a the basfs of infrared
spectra and MR, was separated in pure state.

termined to be 15.5 kcal/mol. The influence

of temperature and the solvent on the position
of the tautomeric equilibrium was studied by
the refractometric method: the equilibrium
shifts somewhat to the side of the cC-form. at
the increase of the temperature, as well as
in pyridine or dioxana. The facility of the
process of the reversible isomerization of
the enamino and amido forms Is explained by
the fAct.that both the tautomeric forms of
.,0-;-amin6vinyl ketones have a forked structure
including a hydrogen bond. The ct,-form, of I
was obtained by the distillation of I with
cooling the condensers to -200 and the co,llec-
tors to -250- 1 in this form is white crystal-
line, the meiting point is 11 to 130. In order
to prepare tort.-butyl.-)O-aminovinyl ketone (II),
