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 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.
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.
According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well (e.g. amides), but not according to the IUPAC. [ 1 ] An example of an ester formation is the substitution reaction between a carboxylic acid ( R−C(=O)−OH ) and an alcohol (R'OH), forming an ester ( R−C(=O)−O−R' ), where R and R′ are ...
Diethyl phosphite is the organophosphorus compound with the formula (C 2 H 5 O) 2 P(O)H. It is a popular reagent for generating other organophosphorus compounds, exploiting the high reactivity of the P-H bond.
[2] [3] This reaction is widely used for the synthesis of various phosphonates, phosphinates, and phosphine oxides. Several reviews have been published. [4] [5] The reaction also occurs for coordinated phosphite ligands, as illustrated by the demethylation of {(C 5 H 5)Co[(CH 3 O) 3 P] 3} 2+ to give {(C 5 H 5)Co[(CH 3 O) 2 PO] 3} −, which is ...
Phosphate esters have the general structure P(=O)(OR) 3 feature P(V). Such species are of technological importance as flame retardant agents, and plasticizers.Lacking a P−C bond, these compounds are in the technical sense not organophosphorus compounds but esters of phosphoric acid.
A phosphite anion or phosphite in inorganic chemistry usually refers to [HPO 3] 2− but includes [H 2 PO 3] − ([HPO 2 (OH)] −). These anions are the conjugate bases of phosphorous acid (H 3 PO 3). The corresponding salts, e.g. sodium phosphite (Na 2 HPO 3) are reducing in character.
