The most commonly detected VOCs at the agriculture site were bromoform, carbon disulfide, chloroform, p -isopropyltoluene, and meta - and para -xylene, each detected in at least three samples. It is also present in varnishes, solvents and insecticides. While, however, reactions of nucleophiles with CO2 are highly reversible and products are only isolated with very strong nucleophiles, the reactions with CS2 are thermodynamically more favored allowing the formation of products with less reactive nucleophiles. It is a widely used solvent, e.g., for rubber, and is used to treat alkali cellulose in the … Various local effects and symptoms may occur from exposure to carbon disulfide. One example is CpCo(η2-CS2)(PMe3). This conversion proceeds via the intermediacy of thiophosgene, CSCl2.
