Tautomerism of a series of substituted 9-acridinethiones

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

A quantitative estimation of thione-thiol tautomerism in a series of substituted 9-acridinethiones was performed by methods of IR, UV, and mass spectrometry as a function of the aggregated state, temperature, and solvent. It was shown that the thione form predominates in the crystal and gas phase; the position of the equilibrium is ambiguous in solutions.
