摘要: This chapter deals with the synthesis, reactivity, and characterization of five-membered heterocycles containing two sulfur atoms in positions 1 3 ring, that is, 1,3-dithiolylium ions, mesoionic 1,3-dithiol-4-ones 4-thiones, 1,3-dithioles, 1,3-dithiolanes. Aspects reactivity 1,3-dithiole derivatives concern all synthetic manipulations at ring carbon heteroatoms as well substituents attached to these atoms. A large section is devoted tetrathiafulvalenes (TTFs) a special subclass 1,3-dithioles π-extended TTFs, due great interest material sciences compounds, mainly semiconductors, organic metals, superconductors, progress made their investigations. New applications medicine, bioorganic enzymatic chemistry are also discussed. An emphasis put on theoretical experimental methods new procedures for 1,3-dithiolane protection deprotection carbonyl groups, which have been developed reviewed period.
