Since a radical mechanism has been proved, it is postulated that radicals result from keto hydroperoxides which have been formed from the aryl-substituted enols via autoxidation. Steric effects and resonance may partly account for differences in the catalytic activity of some and for the inhibiting ...
DURING some polarographical investigations of certain 伪-aminoketones 1 and on the elimination of Mannich bases 2 experimental data were gathered, which can be explained by the occurrence of keto-enol transformation. Though considerable attention has been paid to the mechanism of polarographical ...

The population of subsurface H is also accompanied by a change in the mechanism of enol stabilization via hydrogen bonding: while in the presence of subsurface H specific enol-containing dimers are predominately formed, which strongly interact via the enol-acetyl or enol鈥揺nol groups, in the ...
yet they are very successful in nature. Although the C4carbon pathway is more efficient than the C3pathway at the leaf level and appears to have evolved as a mechanism that promotes reduced photorespiration (Ehleringer and Monson, 1993), C4metabolism often seems to provide littleadvantage at the...

(0) complex, leading to carboradicals formation via the C–O bond fragmentation. In this work, the radical mechanism was scrutinized by using TEMPO as radical trap. When the “3a+6c” reaction was performed in the presence of TEMPO (2.0 equiv), the7cformation was completed suppressed with ...
