Uses

Used in Agricultural Industry:
SALITHION is used as an insecticide and acaricide for controlling a variety of insect and mite pests on crops such as cotton, rice, and vegetables. Its application reason is to protect these crops from damage caused by pests, thereby ensuring a healthy and productive agricultural yield.
However, due to the high toxicity of SALITHION, it is crucial to handle and apply it properly to minimize its impact on the environment and human health. This includes adhering to regulations and restrictions in place to safeguard both the ecosystem and the well-being of individuals involved in its application.

Pesticidal composition containing a microencapsulated organo-phosphorus or carbamate in a pyrethroid dispersion

An insecticidal and/or acaricidal and/or nematicidal composition having a rapid efficacy and residual activity which comprises a mixture of a poorly water-soluble organophosphorus insecticide and/or acaricide and/or nematicide and/or a poorly water-soluble carbamate insecticide and/or acaricide which have been microencapsulated in water-insoluble polymer coatings with a dispersing agent used in forming a microcapsule part, with a poorly water-soluble pyrethroid insecticide and/or acaricide emulsified or suspended in water with the above-mentioned dispersing agent used in forming a flowable part.

Synthesis of 2-Methoxy-4H-1,3,2-benzodioxaphosphorin 2-Sulfide and related Compounds Utilizing Intramolecular Cyclization Reactions

The insecticide salithion (2-methoxy-4H-1,3,2-benzodioxaphosphorin 2-sulfide) and its 4-cyano derivatives were prepared in good yields by utilizing an intramolecular cyclization reaction as the key step.The structures of diastereomers of the 4-cyano derivatives were characterized on the basis of NMR spectroscopy and X-ray analysis.

Synthesis of Optically Active Cyclic Phosphorothionates and Phosphoramidothionates with Insecticidal Activity by Using a Chiral Phosphorylating Agent

Chiral methyl p-nitrophenyl phosphorochloridothionate (MNPC) was utilized as a phosphorylating agent in the synthesis of optically active cyclic phosphorus esters including the enantiomers of 2-methoxy-4H-1,3,2-benzodioxaphosphorin 2-sulfide (salithion) and four diastereomers of 4-isobutyl-2-methoxy-1,3,2-oxazaphospholidine 2-sulfide (BMOS).Their insecticidal activity decreased in the following order; (S) > (R) in salithion and (S)P(S)C > (S)P(R)C > (R)P(R)C > (R)P(S)C in BMOS.
