  2. Zinc compounds - Wikipedia

    en.wikipedia.org/wiki/Zinc_compounds

    Zinc is a strong reducing agent with a standard redox potential of −0.76 V. Pure zinc tarnishes rapidly in air, rapidly forming a passive layer. The composition of this layer can be complex, but one constituent is probably basic zinc carbonate, Zn 5 (OH) 6 CO 3. [8] The reaction of zinc with water is slowed by this passive layer.

  3. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .

  4. Tetrachlorozincate - Wikipedia

    en.wikipedia.org/wiki/Tetrachlorozincate

    Related to the preparation of Lucas' reagent, tetrachlorozincates are often generated by combining hydrochloric acid and zinc chloride. A related anion is [Zn 2 Cl 6] 2−, in which again Zn(II) adopts a tetrahedral geometry. [2] Portion of the crystal structure of the salt hexaacetonitrilenickel(II) tetrachlorozincate ([Ni(CH 3 CN) 6] 2+ [ZnCl ...

  5. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  6. Organozinc chemistry - Wikipedia

    en.wikipedia.org/wiki/Organozinc_chemistry

    The reaction produces a primary, secondary, or tertiary alcohol via a 1,2-addition. The Barbier reaction is advantageous because it is a one-pot process: the organozinc reagent is generated in the presence of the carbonyl substrate. Organozinc reagents are also less water sensitive, thus this reaction can be conducted in water.

  7. Reformatsky reaction - Wikipedia

    en.wikipedia.org/wiki/Reformatsky_reaction

    The Reformatsky reaction (sometimes transliterated as Reformatskii reaction) is an organic reaction which condenses aldehydes or ketones with α-halo esters using metallic zinc to form β-hydroxy-esters: [1] [2] The Reformatsky reaction. The organozinc reagent, also called a 'Reformatsky enolate', is prepared by treating an alpha-halo ester ...

  8. Negishi coupling - Wikipedia

    en.wikipedia.org/wiki/Negishi_coupling

    The major drawback of the Negishi coupling, aside from its water and oxygen sensitivity, is its relative lack of functional group tolerance when compared to other cross-coupling reactions. [ 39 ] (−)-stemoamide is a natural product found in the root extracts of ‘’Stemona tuberosa’’.

  9. Zinc cyanide - Wikipedia

    en.wikipedia.org/wiki/Zinc_cyanide

    Zinc cyanide is the inorganic compound with the formula Zn 2. It is a white solid that is used mainly for electroplating zinc but also has more specialized applications for the synthesis of organic compounds .
