Abstract New 1,3-dithiolium derivatives have been synthesized by heterocyclocondensation of various 3-methylpiperidinyl carbodithioates derived from 2-hydroxypropiophenones. Thus, 1,3-dithiolium perchlorates have been obtained by the treatment of the corresponding dithiocarbamates with a mixture of acetic and sulfuric acid, followed by the addition of perchloric acid. 1,3-Dithiolium perchlorates have been converted to the corresponding 2-(1,3-dithiolium) phenolates under weak basic conditions. These phenolates exhibit mesoionic character with an internal charge transfer absorption band.

Intervalence Charge Transfer

A transition of mixed-valence systems from Class II to Class III crossing the Class II–III borderline is achieved by four thienylene-bridged Mo2 dimers, and is probed using spectral parameters of intervalence charge transfer absorption (band energy, intensity and shape). This study offers fresh and detailed observations of optical behaviors of MV compounds in different regimes.
