  2. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    When the reaction is conducted in dichloromethane, the salt NaBF 4 precipitates and the B(C 6 F 5) 4 - salt remains in solution. Metathesis reactions can occur between two inorganic salts when one product is insoluble in water. For example, the precipitation of silver chloride from a mixture of silver nitrate and cobalt hexammine chloride ...

  3. Potassium chlorate - Wikipedia

    en.wikipedia.org/wiki/Potassium_chlorate

    The low solubility of KClO 3 in water causes the salt to conveniently isolate itself from the reaction mixture by simply precipitating out of solution. Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride: [7] 3 NaOCl → 2 NaCl + NaClO 3

    The compound [(thf) 3 Ca{μ-C 6 H 3-1,3,5-Ph 3}Ca(thf) 3] also described in 2009 [22] [23] is an inverse sandwich compound with two calcium atoms at either side of an arene. Olefins tethered to cyclopentadienyl ligands have been shown to coordinate to calcium(II), strontium(II), and barium(II): [24] Organocalcium compounds have been ...

    Benzenediazonium tetrafluoroborate is an organic compound with the formula [C 6 H 5 N 2]BF 4. It is a salt of a diazonium cation and tetrafluoroborate. It exists as a colourless solid that is soluble in polar solvents. It is the parent member of the aryldiazonium compounds, [1] which are widely used in organic chemistry.

  7. Transition metal thiolate complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_thiolate...

    The salt metathesis reaction route is common. In this method, an alkali metal thiolate is treated with a transition metal halide to produce an alkali metal halide and the metal thiolate complex: LiSC 6 H 5 + CuI → Cu(SC 6 H 5) + LiI. Lithium tert-butylthiolate reacts with MoCl 4 to give the tetrathiolate complex: [3] MoCl 4 + 4 t-BuSLi → Mo ...

  9. Petasis reagent - Wikipedia

    en.wikipedia.org/wiki/Petasis_reagent

    The Petasis reagent is prepared by the salt metathesis reaction of methylmagnesium chloride or methyllithium [2] with titanocene dichloride: [3] Cp 2 TiCl 2 + 2 CH 3 MgCl → Cp 2 Ti(CH 3) 2 + 2 MgCl 2. This compound is used for the transformation of carbonyl groups to terminal alkenes. It exhibits similar reactivity to the Tebbe reagent and ...
