  2. Dichlorine monoxide - Wikipedia

    en.wikipedia.org/wiki/Dichlorine_monoxide

    The earliest method of synthesis was to treat mercury(II) oxide with chlorine gas. [3] However, this method is expensive, as well as highly dangerous due to the risk of mercury poisoning. 2 Cl 2 + HgO → HgCl 2 + Cl 2 O. A safer and more convenient method of production is the reaction of chlorine gas with hydrated sodium carbonate at 20–30 ...

  3. Ruthenium tetroxide - Wikipedia

    en.wikipedia.org/wiki/Ruthenium_tetroxide

    Because the fragments formed are themselves readily oxidizable by RuO 4, a substantial fraction of the arene carbon atoms undergo exhaustive oxidation to form carbon dioxide. Consequently, multiple equivalents of the terminal oxidant (often in excess of 10 equivalents per aryl ring) are required to achieve complete conversion to the carboxylic ...

    dichlorine trioxide, Cl 2 O 3 as O−Cl−ClO 2, chlorine (III,V) oxide dichlorine trioxide, Cl 2 O 3 as possible isomer Cl−O−ClO 2, chlorine (I,V) oxide; dichlorine trioxide, Cl 2 O 3 as hypothetical isomer O−Cl−O−Cl−O, chlorine (III) oxide; dichlorine tetroxide, also known as chlorine perchlorate, Cl 2 O 4 or ClOClO 3, chlorine (I ...

  6. Carbothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Carbothermic_reaction

    Carbothermal reactions produce carbon monoxide (CO) and sometimes carbon dioxide (CO 2). The facility of these conversions is attributable to the entropy of reaction: two solids, the metal oxide (and flux) and carbon, are converted to a new solid (metal) and a gas (CO x), the latter having high entropy.

  7. Dichlorocarbene - Wikipedia

    en.wikipedia.org/wiki/Dichlorocarbene

    Dichlorocarbene is an intermediate in the carbylamine reaction.In this conversion, a dichloromethane solution of a primary amine is treated with chloroform and aqueous sodium hydroxide in the presence of catalytic amount of the phase-transfer catalyst.

  8. Sonogashira coupling - Wikipedia

    en.wikipedia.org/wiki/Sonogashira_coupling

    For instance, oxidation of triphenylphosphine to triphenylphosphine oxide can lead to the formation of Pd 0 in situ when [Pd(PPh 3) 2 Cl 2] is used. Copper(I) salts, such as CuI, react with the terminal alkyne and produce a copper(I) acetylide, which acts as an activated species for the coupling reactions. Cu(I) is a co-catalyst in the reaction ...

  9. Sodium oxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_oxide

    The structure of sodium oxide has been determined by X-ray crystallography.Most alkali metal oxides M 2 O (M = Li, Na, K, Rb) crystallise in the antifluorite structure.In this motif the positions of the anions and cations are reversed relative to their positions in CaF 2, with sodium ions tetrahedrally coordinated to 4 oxide ions and oxide cubically coordinated to 8 sodium ions.
