A novel approach to stimuli-responsive gel termed the "keto-enol tautomerization"-based response mechanism was proposed. By tautomerization, vinyl ketone-based gelator G3 can be self-assembled into an organogel (OG3) accompanied by strong AIE. OG3 shows reversible dual-channel response for S(2-...
By employing infrared reflection adsorption spectroscopy in combination with scanning tunneling microscopy, we found that enol can be formed by building a ketone-enol dimer, in which one molecule in the enol form is stabilized through hydrogen bonding to the carbonyl group of the second ketone ...

These estimates are based upon rapid titrations of the nitroalkane/aci-nitroalkane with molecular bromine similar to the classic method of estimating the amount of an enol present in a enol/ketone mixture. We have reinvestigated the tautomerization by the method of NMR spectroscopy and have found...

In contrast, in the solid state, X-ray analysis revealed that 2 bound 3 with high specificity through intermolecular hydrogen bonds and π–π interactions, and both 2 and 3 tautomerized to a non-symmetric enol–ketone form due to the strong linear hydrogen bonding between the ketone group ...

Summary For a tautomerization to occur spontaneously in one direction, it must be exergonic, and the barrier must be small enough to be overcome at the temperature of the experiment that is used to probe the process. In neutral keto-enol tautomerizations, the direction of the spontaneous ...
