Determination of Relative Tautomer Ratios of 1,3-Indandione in Different Solvents by FT-IR and Computational Methods

Year 2013, Volume: 15 Issue: 1, 11 - 20, 01.06.2013

Abstract

The tautomeric ratios of 1,3-indandione were determined in different solvents (CH3CN, C6H6, MeOH, THF, CCl4, CHCl3, DCM) by means of both experimental FT-IR and computational IR methods. It is found that the keto tautomer is more stable than enol tautomer in all solvents and DCM is the best solvent for the stabilization of enol tautomer (%28)
