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.
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.
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.
Its chemical formula is CH 3 POF 2. It is a Schedule 1 substance under the Chemical Weapons Convention . It is used for production of sarin and soman as a component of binary chemical weapons ; an example is the M687 artillery shell, where it is used together with a mixture of isopropyl alcohol and isopropyl amine , producing sarin .
Dichlorophenylphosphine is an organophosphorus compound with the formula C 6 H 5 PCl 2. This colourless viscous liquid is commonly used in the synthesis of organophosphines. Dichlorophenylphosphine is commercially available. It may be prepared by an electrophilic substitution of benzene by phosphorus trichloride, catalyzed by aluminium chloride.
Dichlorobis(triphenylphosphine)nickel(II) refers to a pair of metal phosphine complexes with the formula NiCl 2 [P(C 6 H 5) 3] 2. The compound exists as two isomers, a paramagnetic dark blue solid and a diamagnetic red solid. These complexes function as catalysts for organic synthesis. [1]
