  2. Lead (II) acetate - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_acetate

    Its chemical formula is usually expressed as Pb(CH 3 COO) 2 or Pb(OAc) 2, where Ac represents the acetyl group. Like many other lead compounds, it causes lead poisoning. Lead acetate is soluble in water and glycerin. With water it forms the trihydrate, Pb(OAc) 2 ·3H 2 O, a colourless or white efflorescent monoclinic crystalline substance.

    For example, (CH 3) 2 CHCH 3, commonly known as isobutane, is treated as a propane chain with a methyl group bonded to the middle (2) carbon, and given the systematic name 2-methylpropane. However, although the name 2-methylpropane could be used, it is easier and more logical to call it simply methylpropane – the methyl group could not ...

  4. Palladium(II) acetate - Wikipedia

    en.wikipedia.org/wiki/Palladium(II)_acetate

    Palladium(II) acetate is a chemical compound of palladium described by the formula [Pd(O 2 CCH 3) 2] n, abbreviated [Pd(OAc) 2] n. It is more reactive than the analogous platinum compound. Depending on the value of n, the compound is soluble in many organic solvents and is commonly used as a catalyst for organic reactions. [2]

  5. Lead(IV) acetate - Wikipedia

    en.wikipedia.org/wiki/Lead(IV)_acetate

    It is typically prepared by treating of red lead with acetic acid and acetic anhydride (Ac 2 O), which absorbs water. The net reaction is shown: [4] [5] Pb 3 O 4 + 4 Ac 2 O → Pb(OAc) 4 + 2 Pb(OAc) 2. The remaining lead(II) acetate can be partially oxidized to the tetraacetate by Cl 2, with a PbCl 2 by-product: 2 Pb(OAc) 2 + Cl 2Pb(OAc) 4 ...

    Iodine-based reagents such as periodic acid (HIO 4) and (diacetoxyiodo)benzene (PhI(OAc) 2) are commonly used. [3] Another reagent is lead tetraacetate (Pb(OAc) 4). [4] These I- and Pb-based methods are called the Malaprade reaction and Criegee oxidation, respectively. The former is favored for aqueous solutions, the latter for nonaqueous ...

    ch 3 oc 6 h 5 + pb(oac) 4 → ch 3 oc 6 h 4 pb(oac) 3 + hoac The reaction is accelerated in the presence of dichloroacetic acid , which forms the lead(IV) dichloroacetate as an intermediate. Other organolead compounds are the halides of the type R n PbX (4-n) , sulfinates (R n Pb(OSOR) (4−n) ) and hydroxides (R n Pb(OH) (4−n) ).

  9. Alcohol oxidation - Wikipedia

    en.wikipedia.org/wiki/Alcohol_oxidation

    [2] In the laboratory, vicinal diols suffer oxidative breakage at a carbon-carbon bond with some oxidants such as sodium periodate (NaIO 4), (diacetoxyiodo)benzene (PhI(OAc) 2) [9] or lead tetraacetate (Pb(OAc) 4), resulting in generation of two carbonyl groups. The reaction is also known as glycol cleavage.
