Mixed Solvent Chemistry through Synergistic Solvation: Structure, Property and Function of t-Butanol-Dichloromethane Binary Solvent Mixtures

摘要

The present study elucidates the synergetic solvation behavior of t-butanol-dichloromethane (t-BuOH-DCM) binary solvent mixtures. UV-visible absorption, emission and H-1-NMR spectroscopy along with analytical modelling were used to ascertain the nature of interactions present, which are found to be maximum at X (t-BuOH) = 0.40, leading to a super solvation environment. The increased polarity of the t-BuOH-DCM binary solvent mixtures through interactive solvent association is believed provide a unique reaction medium that can alter the fate of chemical processes involving a polar species. This idea has been demonstrated by the transformation of merocyanine to 1',3'-dihydro-,1',3',3'-trimethyl-6-nitropiro[2H-1-benzopyran-2,2'-(2H)-indole] and the oxidation of cholestanol to cholestanone.
