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.
[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.
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 2 → Pb(OAc) 4 ...
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]
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) ).
