  2. Thionyl chloride - Wikipedia

    en.wikipedia.org/wiki/Thionyl_chloride

    Thionyl chloride is an inorganic compound with the chemical formula SOCl 2.It is a moderately volatile, colourless liquid with an unpleasant acrid odour.Thionyl chloride is primarily used as a chlorinating reagent, with approximately 45,000 tonnes (50,000 short tons) per year being produced during the early 1990s, [5] but is occasionally also used as a solvent.

  3. Thiophosgene - Wikipedia

    en.wikipedia.org/wiki/Thiophosgene

    Thiophosgene is also known as the appropriate reagent in Corey-Winter synthesis for stereospecific conversion of 1,2-diols into alkenes. [6] It forms a head-to-tail dimer upon irradiation with UV light: 2 CSCl 2 → S 2 (CCl 2) 2. Unlike thiophosgene monomer, a red liquid, the photodimer, an example of a 1,3-dithietane, is a colourless solid. [7]

  4. Thionyl group - Wikipedia

    en.wikipedia.org/wiki/Thionyl_group

    It occurs in compounds such as thionyl fluoride, SOF 2. Thionyl chloride , SOCl 2 , is a common reagent used in organic synthesis to convert carboxylic acids to acyl chlorides . In organic chemistry , the thionyl group is known as a sulfoxide group or sulfinyl group, and has the general structure RS(=O)R'.

  5. Darzens halogenation - Wikipedia

    en.wikipedia.org/wiki/Darzens_halogenation

    Darzens halogenation is the chemical synthesis of alkyl halides from alcohols via the treatment upon reflux of a large excess of thionyl chloride or thionyl bromide (SOX 2) in the presence of a small amount of a nitrogen base, such as a tertiary amine or pyridine or its corresponding hydrochloride or hydrobromide salt.

  6. Oxohalide - Wikipedia

    en.wikipedia.org/wiki/Oxohalide

    All are easily hydrolyzed. Indeed, thionyl chloride can be used as a dehydration agent as the water molecules are converted into gaseous products, leaving behind the anhydrous solid chloride. [11] MgCl 2 ·6H 2 O + 6 SOCl 2 → MgCl 2 + 6 SO 2 + 12 HCl. Selenium and tellurium form similar compounds and also the oxo-bridged species F 5 AOAF 5 (A ...

  7. Phosphorus trichloride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_trichloride

    Phosphorus trichloride is an inorganic compound with the chemical formula PCl 3. A colorless liquid when pure, it is an important industrial chemical, being used for the manufacture of phosphites and other organophosphorus compounds. It is toxic and reacts readily with water to release hydrogen chloride.

  8. von Braun amide degradation - Wikipedia

    en.wikipedia.org/wiki/Von_Braun_amide_degradation

    The von Braun amide degradation is the chemical reaction of a monosubstituted amide with phosphorus pentachloride or thionyl chloride to give a nitrile and an organohalide. [1] It is named after Julius Jacob von Braun, who first reported the reaction. [2] [3] The von Braun amide degradation

  9. Hurd–Mori 1,2,3-thiadiazole synthesis - Wikipedia

    en.wikipedia.org/wiki/Hurd–Mori_1,2,3...

    The Hurd–Mori 1,2,3-thiadiazole synthesis is a name reaction in organic chemistry that allows for the generation of 1,2,3-thiadiazoles through the reaction of hydrazone derivatives with an N-acyl or N-tosyl group reacted with thionyl chloride.
