General description

Carbon disulfide is a widely used solvent in the production of rayon fibers, carbon tetrachloride, pesticides, vulcanizers, cellophane, adhesives, and other chemicals. It is also used as a starting material in the synthesis of various sulfur-containing derivatives.

Application

Carbon disulfide can be used as a solvent:
  • To synthesize hydroxynaphthyl ketones via Friedel-Crafts acylation and demethylation.
  • In the regioselective bromination of binaphthols.

In carotenoids internal conversion between the allowed (S(2)) and forbidden (S(1)) excited states occurs on a sub-picosecond timescale; the involvement of an intermediate excited state(s) (S(x)) mediating the process is controversial. Here we use high time resolution (sub-20 fs) broadband

Extremophilic organisms require specialized enzymes for their exotic metabolisms. Acid-loving thermophilic Archaea that live in the mudpots of volcanic solfataras obtain their energy from reduced sulphur compounds such as hydrogen sulphide (H(2)S) and carbon disulphide (CS(2)).

Electronic core levels in molecules are highly localized around one atomic site. However, in single-photon ionization of symmetric molecules, the question of core-hole localization versus delocalization over two equivalent atoms has long been debated as the answer lies at the
