  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 ...

  3. Michaelis–Arbuzov reaction - Wikipedia

    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.

  4. Organophosphorus chemistry - Wikipedia

    en.wikipedia.org/wiki/Organophosphorus_chemistry

    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. Many derivatives are found in nature, such as ...

  5. Tris(2,4-di-tert-butylphenyl)phosphite - Wikipedia

    en.wikipedia.org/wiki/Tris(2,4-di-tert-butyl...

    Tris(2,4-di-tert-butylphenyl)phosphite is an organophosphorus compound with the formula [(C 4 H 9) 2 C 6 H 3 O] 3 P. This white solid is a widely used stabilizer in polymers where it functions as a secondary antioxidant. It also reduces discoloration (yellowing) of plastics.

  6. Exogenous ketone - Wikipedia

    en.wikipedia.org/wiki/Exogenous_ketone

    Technically there are other ketone esters such as acetoacetate bound to D/L 1,3-butanediol (racemic). This diester has been tested more with deep sea divers. It is not commercially available. [10] Another ketone ester is also referred to as a ketone di-ester which is a bond of C6 and R 1,3 butanediol or C8 and R 1,3 butanediol.

  7. Phosphonate - Wikipedia

    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).

  8. Setting spray - Wikipedia

    en.wikipedia.org/wiki/Setting_spray

    Setting spray (also finishing spray, makeup setting spray, finish spray, or makeup spray) is a cosmetic product designed to preserve applied make-up in place for long periods of time. Usually sold in small spray bottles, setting spray is applied by spritzing mist over the face, keeping the make-up application moist for several hours.

  9. Büchner–Curtius–Schlotterbeck reaction - Wikipedia

    en.wikipedia.org/wiki/Büchner–Curtius...

    The Buchner–Curtius–Schlotterbeck reaction is the reaction of aldehydes or ketones with aliphatic diazoalkanes to form homologated ketones. [1] It was first described by Eduard Buchner and Theodor Curtius in 1885 [2] and later by Fritz Schlotterbeck in 1907. [3]
