Methylphosphonyl dichloride (DC) or dichloro is an organophosphorus compound. It has commercial application in oligonucleotide synthesis, [1] but is most notable as being a precursor to several chemical weapons agents. It is a white crystalline solid that melts slightly above room temperature. [2]
Methyl phosphonous dichloride, Dichloromethylphosphine, SW [1 ... The compound is an intermediate for the synthesis of other chemicals for instance ...
It will react with thionyl chloride to produce methylphosphonic acid dichloride, which is used in the production of sarin and soman nerve agents. Various amines can be used to catalyse this process. [3] It can be used as a sarin-simulant for the calibration of organophosphorus detectors.
Most processes begin with phosphorous acid (aka phosphonic acid, H 3 PO 3), exploiting its reactive P−H bond. [1] [3]Phosphonic acid can be alkylated via the Kabachnik–Fields reaction or Pudovik reaction to give aminophosphonate, which are useful as chelating agents.
The compound exhibits the properties characteristic of a primary phosphine, i.e., a compound of the type RPH 2.It can be oxidized to methylphosphonous acid: . MePH 2 + O 2 → MeP(H)O 2 H
Methylphosphonic acid is an organophosphorus compound with the chemical formula CH 3 P(O)(OH) 2. The phosphorus center is tetrahedral and is bonded to a methyl group, two OH groups and an oxygen. Methylphosphonic acid is a white, non-volatile solid that is poorly soluble in organic solvent but soluble in water and common alcohols.
Selenium plays important roles in hormone function, a healthy metabolism, DNA synthesis and protection from oxidative damage and infection, notes the U.S. National Institutes of Health (NIH ...
The compound is an intermediate for the synthesis of other chemicals for instance dimethylphenylphosphine: C 6 H 5 PCl 2 + 2 CH 3 MgI → C 6 H 5 P(CH 3) 2 + 2 MgICl. Many tertiary phosphines can be prepared by this route. [3] In the McCormack reaction dichlorophenylphosphine adds dienes to give the chlorophospholenium ring. [4]
