2005a), as it would likewise work for inner and outer ring deiodination. In contrast, keto–enol tautomerization is only possible in the outer ring (Goto et al. 2010, Manna et al. 2015). Accordingly, a keto–enol mechanism for 5′-deiodination would call for an entirely different ...
The relaxation of keto* results in the ground-state keto structure that undergoes a reverse ground state proton transfer back to enol species. It is the primary changes about electronic structures and charge dis- tributions under the photoexcitation, ESPT processes own obviously different ...
The example on Wikipedia is very confusing because they are leaving out the keto-enol tautomerization steps. Perkow_reaction.png (35.21 kB, 3902x1125 - viewed 497 times.) Logged orgopete Chemist Sr. Member Posts: 2636 Mole Snacks: +213/-71 Re: what's the mechanism? « Reply #3 ...
a model compound of phenolics, on Ni(1 1 1) and NiFe(1 1 1) surfaces using periodic density functional theory calculations and microkinetic modeling techniques, with a focus on the several competing reaction pathways including enol-keto tautomerization, hydrogenation, and dehydroxylation. Ou...
After dissociation from the dehydratase active site and diffusion into the solution, this enol sugar will facilely rearrange to give the more favorable dTDP-4-keto-6-dexoyglucose product. Although Thr127 is not directly involved in the whole enzymatic reaction, it is responsible for promoting the...
Several mechanisms have been proposed to explain the variations of the bioluminescence color for native and mutant luciferases. According to White at al1changes in bioluminescence spectra are the result of keto-enol tautomerization of oxyluciferin(LO). The efficiency of this process depends on a ...
