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.
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]
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 ...
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) ).
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 ...
Antimony(III) acetate is the compound of antimony with the chemical formula of Sb(CH 3 CO 2) 3. It is a white powder, is moderately water-soluble, and is used as a catalyst in the production of polyesters .

Basic beryllium acetate has a tetrahedral Be 4 O 6+ core with acetates (CH 3 CO 2 −) spanning each of the pairs of Be 2+ centres. [3] [4] It consists of interlocking six-membered Be 2 O 3 C rings. The structure is relevant to its considerable stability (the compound is distillable at 330 °C). Schematic structure of basic beryllium acetate
