  2. Phosphite ester - Wikipedia

    en.wikipedia.org/wiki/Phosphite_ester

    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 ...

    en.wikipedia.org/wiki/Phosphite_anion

    From the commercial perspective, the most important phosphite salt is basic lead phosphite. Many salts containing the phosphite ion have been investigated structurally, these include sodium phosphite pentahydrate (Na 2 HPO 3 ·5H 2 O). (NH 4) 2 HPO 3 ·H 2 O, CuHPO 3 ·H 2 O, SnHPO 3 and Al 2 (HPO 3) 3 ·4H 2 O. [4] The structure of HPO 2− 3 ...

    en.wikipedia.org/wiki/Michaelis–Arbuzov_reaction

    Phosphite esters with tertiary alkyl halide groups can undergo the reaction, which would be unexpected if only an S N 2 mechanism was operating. Further support for this S N 1 type mechanism comes from the use of the Arbuzov reaction in the synthesis of neopentyl halides, a class of compounds that are notoriously unreactive towards S N 2 reactions.

  5. Perkow reaction - Wikipedia

    en.wikipedia.org/wiki/Perkow_reaction

    Key in explaining the difference in reactivity is the electron density on the α-keto carbon atom. Perkow quinoline application Aryl enol phosphates formed in good yields (ca. 90%) in the Perkow reaction can be used as phosphorylating reagents, e.g. able to transform AMP into ATP .

  6. Phosphorus trichloride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_trichloride

    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 ...

  7. Triethyl phosphite - Wikipedia

    en.wikipedia.org/wiki/Triethyl_phosphite

    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.

    en.wikipedia.org/wiki/Phosphonate

    General ester of phosphonic acid; in fact, the phosphorus has a formal charge of +1, the oxygen above it has a formal charge of −1, and the bond between them is single. In organic chemistry , phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR) 2 groups , where R is an organic group ( alkyl , aryl ).
