Description
Summary:The present study elucidates the synergetic solvation behavior of t -butanol–dichloromethane ( t -BuOH–DCM) binary solvent mixtures. UV–visible absorption, emission and 1 H-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.
