NH 3 + 3 H 3 PO 3 + 3 CH 2 O → N(CH 2 PO 3 H 2) 3 + 3 H 2 O. Phosphonic acid also can be alkylated with acrylic acid derivatives to afford carboxyl functionalized phosphonic acids. This reaction is a variant of the Michael addition: CH 2 =CHCO 2 R + 3 H 3 PO 3 → (HO) 2 P(O)CH 2 CH 2 CO 2 R
[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.

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.
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]
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 .
2,5-Diphenyl phospholes can be functionalised by deprotonation followed by P-acylation then a 1H, 2H, 3H phospholide equilibrium resulting in a 1:3 shift of the acyl group. [ 9 ] Phospholes can also be turned into β-functional phosphabenzenes (phosphinines, or phosphorine ) via functionalisation by imidoyl chloride and insertion .
