Tin-Containing π-Electron Systems

Abstract

Introduction of tin atom into the carbon π-conjugated systems is expected to express the unique properties derived from their small HOMO–LUMO gaps and so on. However, the chemistry of tin-containing π-conjugated systems has been less studied in comparison with the silicon- and germanium-containing systems due to their instability. Recently, the development of the synthetic and stabilization methods enables us to access to the tin-containing systems. In this chapter, the chemistry of tin-containing π-electron systems, stannapentafulvenes, stannacyclopentadienides, and neutral stannaaromatic compounds will be discussed.
