The general structure of a phosphite ester showing the lone pairs on the P. In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR) 3. They can be considered as esters of an unobserved tautomer phosphorous acid, H 3 PO 3, with the simplest example being trimethylphosphite ...
Triethyl phosphite (TEP) is an organophosphorus compound, specifically a phosphite ester, with the formula P(OCH 2 CH 3) 3, often abbreviated P(OEt) 3. It is a colorless, malodorous liquid. It is used as a ligand in organometallic chemistry and as a reagent in organic synthesis.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
Diethyl phosphite hydrolyzes to give phosphorous acid. Hydrogen chloride accelerates this conversion.: [2] Diethyl phosphite undergoes transesterification upon treating with an alcohol. For alcohols of high boiling points, the conversion can be driven by removal of ethanol: [8] (C 2 H 5 O) 2 P(O)H + 2 ROH → (RO) 2 P(O)H + 2 C 2 H 5 OH
The phosphite esters and tertiary phosphines also effect reduction: ROOH + PR 3 → P(OR) 3 + ROH Cleavage to ketones and alcohols occurs in the base-catalyzed Kornblum–DeLaMare rearrangement , which involves the breaking of bonds within peroxides to form these products.
It reacts with phenol to give triphenyl phosphite: 3 PhOH + PCl 3 → P(OPh) 3 + 3 HCl (Ph = C 6 H 5) Alcohols such as ethanol react similarly in the presence of a base such as a tertiary amine: [9] PCl 3 + 3 EtOH + 3 R 3 N → P(OEt) 3 + 3 R 3 NH + Cl −. With one equivalent of alcohol and in the absence of base, the first product is ...
The following compounds are liquid at room temperature and are completely miscible with water; ... furfuryl alcohol: 98-00-0 C 3 H 8 O 3: glycerol: 56-81-5 CH 3 OH ...
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.
