Uses

Used in Agricultural Industry:
Trimethyl (phosphorothioyltrimethanediyl)triscarbamate is used as an insecticide and acaricide for controlling a variety of pests such as mites, aphids, and caterpillars. It operates by disrupting the nervous system of the target pests, resulting in paralysis and ultimately death. Recognized for its high toxicity to insects and comparatively low toxicity to mammals, trimethyl (phosphorothioyltrimethanediyl)triscarbamate offers an effective and relatively safe method for pest management in agriculture. However, adherence to label instructions and safety guidelines is crucial to mitigate any potential risks to human health and the environment.

Process for the preparation of tris(N-carbalkoxylaminomethyl)phosphine oxides and sulfides

The title compounds, having the formula (RO2 CNHCH2)3 PY where Y=oxygen or sulfur, are prepared by reacting a tetrakis(N-carbalkoxylaminomethyl)phosphonium salt having the formula (RO2 CNHCH2)4 P+ X- with ammonia or a primary or secondary amine, followed by an oxidizing or sulfurizing agent. The products, after methylolation with formaldehyde, are useful as finishing agents for imparting flame retardant properties to cotton fabrics.

Synthesis of tris(aminomethyl)phosphine oxide and its carbon dioxide adduct from tetrakis(hydroxymetyl)phosphonium salts via their methyl carbamate derivatives

Tris(aminomethyl)phosphine oxide (6) can be synthesized from octakis(hydroxymethyl)diphosphonium sulfate (1b) in an overall yield of 54.6percent via the methyl carbamate derivatives 2b, 3, and 4.On a preparative scale, the last step is complicated by the formation of a cyclic by-product 8 in amounts up to 20percent of the total.The triamine 6 forms a 1:1 adduct (11) with carbon dioxide, whose structure, established by 1H and 13C nmr, consists of equimolar amounts of carbamate A and dicarbamate BC.The components A, B, and C can be separated by ion exchange.Thjermolysis of 11 regenerates 6 smoontly, providing a convenient method for purifying the triamine.
