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: [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 ...
[2] [3] [4] However, unlike sodium cyanoborohydride, the triacetoxyborohydride hydrolyzes readily, nor is it compatible with methanol. It reacts only slowly with ethanol and isopropanol and can be used with these. [3] Reductive amination with STAB. NaBH(OAc) 3 may also be used for reductive alkylation of secondary amines with aldehyde-bisulfite ...
Since sodium cyanoborohydride is a mild reducing agent, it gives good chemoselectivity for reaction with certain functional groups in the presence of others. For example, sodium cyanoborohydride is generally incapable of reducing amides, ethers, esters and lactones, nitriles, or epoxides. [8]
The anhydrous material and dihydrate Mn(CH 3 CO 2) 2 ·2H 2 O are coordination polymers. The dihydrate has been characterized by X-ray crystallography. Each Mn(II) center is surrounded by six oxygen centers provided by aquo ligands and acetates. Subunit of the structure of the dihydrate of manganese(II) acetate. [5]
Copper(II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc) 2 where AcO − is acetate (CH 3 CO − 2).The hydrated derivative, Cu 2 (OAc) 4 (H 2 O) 2, which contains one molecule of water for each copper atom, is available commercially.
Rhodium(II) acetate is the coordination compound with the formula Rh 2 (AcO) 4, where AcO − is the acetate ion (CH 3 CO − 2). This dark green powder is slightly soluble in polar solvents, including water. It is used as a catalyst for cyclopropanation of alkenes. It is a widely studied example of a transition metal carboxylate complex. [2]
Sodium amalgam, with the common formula Na(Hg), is an alloy of mercury and sodium. The term amalgam is used for alloys, intermetallic compounds, and solutions (both solid solutions and liquid solutions) involving mercury as a major component. Sodium amalgams are often used in reactions as strong reducing agents with better handling properties ...
