The blue colored 1-benzothiopyrylium perchlorates were synthesized by the reduction of thiocoumarins with lithium aluminium hydride followed by the treatment with acid. A number of new thiocarbonyl derivatives of thiocoumarins and thiochromones were also synthesized, the spectral characterization of which has been described.
