Methylphosphonyl dichloride is produced by oxidation of methyldichlorophosphine, with sulfuryl chloride: [3] CH 3 PCl 2 + SO 2 Cl 2 → CH 3 P(O)Cl 2 + SOCl 2. It can also be produced from a range of methylphosphonates (e.g. dimethyl methylphosphonate) via chlorination with thionyl chloride. Various amines catalyse this process. [4]

[2] Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons. 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.

Both cis and trans isomers are known, but the cis isomer is more common. The cis isomer is a yellow, air-stable solid that is soluble in some organic solvents. These sulfoxide complexes are used in the synthesis of various ruthenium(ii) complexes. [1] They have also attracted attention as possible anti-cancer drugs.
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.

Methylphosphonyl difluoride (DF), also known as EA-1251 [2] or difluoro, [3] is a chemical weapon precursor. Its chemical formula is CH 3 POF 2 . It is a Schedule 1 substance under the Chemical Weapons Convention .
This complex was first prepared from hexamethyl Dewar benzene and RhCl 3 (H 2 O) 3. [3] [4] [5] The hydrohalic acid necessary for the ring-contraction rearrangement is generated in situ in methanolic solutions of the rhodium salt, and the second step has been carried out separately, confirming this mechanistic description.
