Kinetics and Dynamics: From Nano- to Bio-Scale
The catalytic effect of this doubly charged metal ion on the tautomeric processes
connecting the diketo forms (1 and 4) with the enolic ones (2a and 5a) is
apparent by comparing the barriers involved in uracil–Ca2+ complexes and
those of the ...

Frontiers of Molecular Spectroscopy
Baughcum and collaborators [47] analyzed the rotational spectrum of
malonaldehyde and showed unambiguously that the molecule adopts Cs
symmetry in an enolic form with a low barrier to proton tunneling. It was much
later that the ...

Polymeric Materials Encyclopedia, Twelve Volume Set
The stronger the substituent, R, in the structure CH,=CH- CO-CH,-R pulls on the
electron, the more the enolic form predominates. In fact, as mentioned previously,
AA is only in the enolic form, whereas ethyl acryloylacetate (EAA) exhibits the ...

The ozone starts its reaction with ketone (probably with the enolic form) and an
abrupt fall of its concentration is registered; 2. When the rate of ozone supply
becomes equal to the rate of the chemical reaction, the first step is formed; 3. The
end ...

Synthesis and Characterization of O-acylnaphthols
(1967) has reported enolic chemical shifts as far downfield as δ 16.6 ppm. For
example, proton NMR has been used to differentiate between the keto and enol
tautomers of acetylacetone 3 at room temperature. The keto-enol conversion is ...
