One-Pot Synthesis of Heterocycle-Fused 1,3-Diselenole-2-selones as the Key Precursors of Tetraselenafulvalene-Type Electron Donors
摘要:
A simple one pot synthetic method of a series of 4,5-alkylenedichalcogeno-substituted 1,3-diselenole-2-selones by successive treatments of trimethylsilylacetylene with butyllithium, selenium, carbon diselenide, and finally alpha,omega-bis(chalcogenocyanato)alkanes is described.

Molecular Modifications of Methylenedithio-Tetraselenafulvalene (MDT-TSF) and Methylenedithio-Diselenadithiafulvalene (MDT-ST) for Superior Electron Donors
The dimethyl-, bis(methylthio)-, and ethylenedithio-derivatives of methylenedithio-tetraselenafulvalene and methylenedithio-diselenadithiafulvalene have been synthesized as new electron donors. The formation and electrical conductivities of their radical cation salts are examined.
