Dimethyl methylphosphonate can be prepared from trimethyl phosphite and a halomethane (e.g. iodomethane) via the Michaelis–Arbuzov reaction. [2]Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons.
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 .
It, along with methylphosphonyl difluoride (DF), was developed during the 1980s in order to replace an aging stockpile of unitary chemical weapons. [3] QL is listed as a Schedule 1 chemical by the Chemical Weapons Convention .
[1] [2] However, aluminum chloride often induces diarylation; a cleaner catalyst for monoarylation is stannic chloride. [2] 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]
