Of two tautomers of 2-mercapto substituted tropone, 2-mercaptotropone and 2-hydroxytropothione, the former is isolated as a 2:1 complex with 1,1,6,6-tetraphenylhexa-2,4-diyne-1,6-diol, and infrared and electronic absorption spectra of the complex are reported.X-Ray crystal structural study shows that the 2-mercaptotropone in the complex has no bond alternation and then has a delocalized ?-electron system.
