The Hg 2+ center binds to alkenes, inducing the addition of hydroxide and alkoxide. For example, treatment of methyl acrylate with mercuric acetate in methanol gives an α-mercuri ester: [6] Hg(OAc) 2 + CH 2 =CHCO 2 CH 3 + CH 3 OH → CH 3 OCH 2 CH(HgOAc)CO 2 CH 3 + HOAc. Exploiting the high affinity of mercury(II) for sulfur ligands, Hg(OAc) 2 ...
In organic chemistry, the oxymercuration reaction is an electrophilic addition reaction that transforms an alkene (R 2 C=CR 2) into a neutral alcohol. In oxymercuration, the alkene reacts with mercuric acetate (AcO−Hg−OAc) in aqueous solution to yield the addition of an acetoxymercury (−HgOAc) group and a hydroxy (−OH) group across the ...
The Hg 2+ center binds to alkenes, inducing the addition of hydroxide and alkoxide. For example, treatment of methyl acrylate with mercuric acetate in methanol gives an α--mercuri ester: [9] Hg(O 2 CCH 3) 2 + CH 2 =CHCO 2 CH 3 → CH 3 OCH 2 CH(HgO 2 CCH 3)CO 2 CH 3. The resulting Hg-C bond can be cleaved with bromine to give the corresponding ...
Haloacetic acids have a general chemical formula X 1 X 2 X 3 C−CO 2 H, where X is hydrogen or halogen, and at least one X is a halogen. The inductive effect caused by the electronegative halogens often results in the higher acidity of these compounds by stabilising the negative charge of the conjugate base .
4-Aminophenylmercuric acetate (CH 3 CO 2 HgC 6 H 4 NH 2, also known as 4-(Acetoxymercurio)aniline or APMA), is an organomercurial compound and thiol-blocking reagent used in experimental biology and chemistry to activate matrix metalloproteinases and collagenase proteolytic enzymes. [1] [2] The material is highly toxic.
Acetyl hypochlorite is reported to be produced by the reaction of acetic anhydride and dichlorine monoxide at very low temperatures: [2]. Cl 2 O + (CH3CO) 2 O → 2CH 3 COOCl. The liquid can be distilled at reduced pressure, however it cannot be heated, as it violently decomposes at 100 °C to acetic anhydride, oxygen, and chlorine gas, and reacts with water and alcohols.
1% and 2% uranyl acetate solutions are used as an indicator, and a titrant in stronger concentrations in analytical chemistry, as it forms an insoluble salt with sodium (the vast majority of sodium salts are water-soluble). Uranyl acetate solutions show evidence of being sensitive to light, especially UV, and will precipitate if exposed.
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.
