Trimethyl phosphite is an organophosphorus compound with the formula P(OCH 3) 3, often abbreviated P(OMe) 3.It is a colorless liquid with a highly pungent odor. It is the simplest phosphite ester and finds used as a ligand in organometallic chemistry and as a reagent in organic synthesis.
Trimethyl phosphate is a mild methylating agent, useful for dimethylation of anilines and related heterocyclic compounds. [2] The method is complementary to the traditional Eschweiler-Clarke reaction in cases where formaldehyde engages in side reactions.
Phosphite esters are typically prepared by treating phosphorus trichloride with an alcohol. For alkyl alcohols the displaced chloride ion can attack the phosphite, causing dealkylation to give a dialkylphosphite and an organochlorine compound. [1] [2] The overall reaction is as follows: PCl 3 + 3 C 2 H 5 OH → (C 2 H 5 O) 2 P(O)H + 2 HCl + C 2 ...
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.
Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride.Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4).
With one equivalent of alcohol and in the absence of base, the first product is alkoxyphosphorodichloridite: [10] PCl 3 + EtOH → PCl 2 (OEt) + HCl. In the absence of base, however, with excess alcohol, phosphorus trichloride converts to diethylphosphite: [11] [12] PCl 3 + 3 EtOH → (EtO) 2 P(O)H + 2 HCl + EtCl. Secondary amines (R 2 NH) form ...
Trimethylolpropane phosphite, C 2 H 5 C(CH 2 O) 3 P, is a phosphite ester used as a ligand in organometallic chemistry. Trimethylolpropane phosphite is sometimes abbreviated to EtCage. It is a white solid that is soluble in organic solvents. It is also highly toxic. [1]
3,5,5-Trimethyl-1-hexanol is a nine carbon primary alcohol, and it makes up the mixture isononanol along with isononyl alcohol. It is used for fragrance in many toiletries and household cleaning products. Between one and ten metric tonnes are produced every year for use as a fragrance. [1]
