  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. Selenium oxydichloride - Wikipedia

    en.wikipedia.org/wiki/Selenium_oxydichloride

    The SeOCl 2 is generally a labile Lewis acid and solutions of sulfur trioxide in SeOCl 2 likely form [SeOCl] + [SO 3 Cl] − the same way. [ 5 ] The compound hydrolyzes readily to form hydrogen chloride and selenium dioxide , [ citation needed ] and very few organic compounds dissolve in it without reaction.

  4. SNi - Wikipedia

    en.wikipedia.org/wiki/SNi

    Some examples for this reaction were reported by Edward S. Lewis and Charles E. Boozer in 1952. [2] Mechanistic and kinetic studies were reported few years later by various researchers. [3] [4] Thionyl chloride first reacts with the alcohol to form an alkyl chloro sulfite, actually forming an intimate ion pair.

  5. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  6. Sulfuryl chloride - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl_chloride

    Sulfuryl chloride is used as a source of Cl 2.Because it is a pourable liquid, it is considered more convenient than Cl 2 to dispense.. Sulfuryl chloride is used in the conversion of C−H to C−Cl adjacent to activating substituents such as carbonyls and sulfoxides: [5] [6]

  7. Thionyl fluoride - Wikipedia

    en.wikipedia.org/wiki/Thionyl_fluoride

    Thionyl fluoride is the inorganic compound with the formula S O F 2.This colourless gas is mainly of theoretical interest, but it is a product of the degradation of sulfur hexafluoride, an insulator in electrical equipment.

  8. HSAB theory - Wikipedia

    en.wikipedia.org/wiki/HSAB_theory

    HSAB is an acronym for "hard and soft (Lewis) acids and bases".HSAB is widely used in chemistry for explaining the stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species.

  9. Acyl chloride - Wikipedia

    en.wikipedia.org/wiki/Acyl_chloride

    General chemical structure of an acyl chloride. In organic chemistry, an acyl chloride (or acid chloride) is an organic compound with the functional group −C(=O)Cl. Their formula is usually written R−COCl, where R is a side chain. They are reactive derivatives of carboxylic acids (R−C(=O)OH).
