A simple computational approach for pKa calculation of organosulfur compounds

نویسندگان

چکیده

The present work is related to predicting the pKa values of organosulfur compounds through density functional theory (DFT). In this study, 22 were considered calculate theoretical values. main emphasis was given on substitution different groups sulfur atom. computations performed in presence dimethyl sulfoxide (DMSO) as solvent. Experimentally, order increase acidity is; sulfides < sulfoxides sulfones. herein computed also follow same order. using DFT method B3LYP, with basis sets 6-31G(d), 6-31+G(d,p) and IEFPCM bulk solvation model. majority diffuse function set excellent agreement experimental ones. Hence computational approach, B3LYP/6-31+G(d,p)/IEFPCM, could be utilized predict these types compounds.

Computational calculation of equilibrium constants: addition to carbonyl compounds.

Hydration reactions are relevant for understanding many organic mechanisms. Since the experimental determination of hydration and hemiacetalization equilibrium constants is fairly complex, computational calculations now offer a useful alternative to experimental measurements. In this work, carbonyl hydration and hemiacetalization constants were calculated from the free energy differences betwee...

A computational molecular approach on chitosan vehicle for metformin

Density functional theory (DFT) calculations have been performed to study properties of chitosan (Chit) as a possible vehicle for carrying metformin (Met) drug. To this aim, the singular molecules of Met and Chit have been first optimized and sixteen possible bimolecular complexes have been subsequently constructed and optimized to obtaine the stabilized interacting structures. Two bimolecular ...
