The amount of enol at equilibrium depends on temperature.
To illustrate the efficiency of DA, the ensemble open-loop (EnOL) cases and the EnKF cases are compared.
The two NMR resonances at 11.81 and 11.28 ppm disappeared after complexation reaction, indicating that the structure of L1 changed from keto to enol conformation and the O atom from phenolic group has bound to the Zn metal center.
To consider all the possible forms of reacting donor species (Figure 6), we calculated the [DELTA]G of the enol forms 5 and 6, the zwitterionic forms (protonated enolates, 7 and 8), a dimer of protonated tropinone and tropinone enolate (9), and the hydrated zwitterionic forms (10 and 11).
There might be differences in these orders due to forming intermolecular hydrogen bonding and forming acid thiol and enol group because of tautomerism in the ligand.
As shown in Figure 3, dual emission is well resolved in the steady-state measurement of 1, which is composed of a normal emission band (enol form), justified by its mirror image with respect to the lowest lying absorption, and a large Stokes shifted (5834 [cm.sup.-1]) emission band maximized at 457 and 574 nm, respectively.

Depending on the actual (and presently unknown) pathway the reaction will require either a hydrogenation of carbonyl intermediates (second step of the top pathway--analogous to the pathway in Figure 2) or enol ethers (bottom pathway) and in either case a hydrogenolysis of a secondary carbon-oxygen bond (first or second step in the top or bottom pathway, respectively).
