Synthesis and Structure of a Novel Alkynyl-Containing Disulfide Compound as Cathode Materials for Secondary Lithium Batteries

Abstract

A novel alkynyl-containing disulfide compound, 5,8-dihydro-1H,4H-2,3,6,7-tetrathia-anthracen (TMSEDTTA), was synthesized. The structures of the target compound and the intermediates have been identified by ¹H NMR, ¹³C NMR, mass spectrometry, Fourier-transform infrared, Raman spectra, x-ray photoelectron spectroscopy, and elemental analysis. In addition, the structure of (Z)-(1,2-dibromo-2-(2,3,5,6-tetrakis(bromomethyl)phenyl)vinyl)trimethylsilane (5) was determined by single x-ray analysis.
