  • Spectral kinetic characteristics of the photoisomerization products of naphthylmethylideneiminospironaphthopyran induced by photolysis at different wavelengths

    The spectral kinetic characteristics of intermediates generated by photolysis with light at the wavelengths 337 and 430 or 470 nm of the photobifunctional compound (PBC), 1,3-dihydro-5-(2-hydroxy-1-naphthylmethylideneimino)-1,3,3-trimethylspiro[2H-indole-2,3-[3H]-naphtho[2,1-b]pyran], whose molecule combines the spironaphthopyran and hydroxyazomethine fragments, and also parameters of model compounds, viz., naphthylmethylideneimine and spironaphthopyran, were studied in methanol and toluene. The relative quantum yields of formation of different intermediates of PBC were measured relatively to model compounds, namely, trans-keto isomer formed due to cis-trans-isomerization and prototropic equiliration in the azomethine fragment, and in the merocyanine form generated by spiro bond opening. It was found that the photolysis of the PBC with light at the wavelengths λ = 430 or 470 nm nearly no produces the merocyanine form, whereas the relative yield of the trans-keto tautomer is ∼0.6. For PBC photolysis at λ = 337 nm, the yield of the merocyanine form is ∼0.2 and the yield of the trans-keto isomer decreases substantially (≤0.2). The solvent nature affects the kinetic behavior of the system. The consistency of the isomerization and proton transfer processes is discussed.

  • Factors determining tautomeric equilibria in Schiff bases
    作者:Martha Flores-Leonar、Nuria Esturau-Escofet、José M. Méndez-Stivalet、Armando Marı´n-Becerra、Carlos Amador-Bedolla

    Schiff bases derived from o-hydroxyaldehydes present keto and enol tautomeric forms: the relative equilibrium between these two tautomers depending on the particular aldehyde the Schiff bases is derived from. Thus benzaldehyde produces a stable enol tautomer, while a naphthaldehyde produces a mixture of keto and enol tautomers. The energy difference between these tautomers is very small (similar to 5 kJ/mol) and therefore close to current precision limits of ab initio and DFT based quantum calculations. NMR spectroscopy results, which allows for the determination of the stable structure when one tautomer is prevalent, can be very difficult to interpret when both tautomers are present. We calculate energy differences between the tautomers and demonstrate that the precision of current DFT calculations is not sufficient to predict the most stable structure. On the other hand, DFT calculations of the NMR chemical shifts (using the CIAO technique) can properly interpret the spectroscopy results allowing the characterization of the experimentally present tautomers and the estimation of the relative abundance of each when both are present.
