Solvent effects on the 17O NMR chemical shifts of 4-dimethylsulfoximide-1,1,1-trifluoro-3-alken-2-ones

17O NMR studies of boronic acids and their derivatives

“…87 This method has been used in previously reported studies of the solvation 17 O NMR shifts. [88][89][90][91][92][93] Phenylboronic acid was used to avoid the effects caused by the interactions of the solvent with the substituent in the aryl ring. Moreover, phenylboronic acid 1,2-ethanediol ester was used for comparison as its molecule does not act as a hydrogen bond donor.…”

Complexation of Molybdenum(VI) with Ethylenediaminediacetic Acid in Different Water + Methanol Solutions

“…Therefore, it is stated that the polarity of a solvent is determined by its solvation capability or (solvation power) for reactants and activated complexes as well as for molecules in their ground and excited states. , Thus, solvation power depends on all specific and nonspecific intermolecular forces between solvent and solute molecules which include Coulomb interactions between ions, directional interactions between dipoles, inductive, dispersion, hydrogen bonding, and charge-transfer forces, as well as solvophobic interactions. A literature survey reveals that in spite of several papers about thermodynamics and kinetics of solutions with different protic and aprotic solvents − there are no reports on the complexation of Mo(VI) with EDDA in different aqueous solutions of methanol. The present study deals with the aforementioned system, and the results have also been compared with similar complexes reported in the literature.…”

Determination of Solvatochromic Regression Coefficients for the Molybdenum(VI) Complex with Ethylenediamine‐N,N′‐diacetic Acid by Using Kamlet‐Abboud‐Taft Equation

“…Until now the complexity of solute-solvent interactions prevented the derivation of generally applicable mathematical equations that make it feasible to calculate the reaction rates or equilibrium constants of reactions carried out in solvents at different polarity, but one of the well-known equations which works very well in this field is Kamlet-Abboud-Taft equation (KAT). Although several papers have been published about application of KAT equation, [1][2][3][4][5][6] there are no reports on the complexation of Mo(VI) with ethylenediamine-N,N'-diacetic acid (EDDA) in different aqueous solutions of methanol by using KAT equation. We have recently published a paper regarding the complexation of Mo(VI) with EDDA in different aqueous solutions of methanol 7 and presented part of the results at the 31st International Conference on Solution Chemistry (ICSC2009).…”
