Salt/common salt – a mineral, sodium chloride, NaCl, formed by evaporating seawater (impure form). Salt of tartar – potassium carbonate; also called potash. Salt of hartshorn/sal volatile – ammonium carbonate formed by distilling bones and horns. Tin salt – hydrated stannous chloride; see also spiritus fumans, another chloride of tin.
Commonly known as magic blue, it is the hexachloroantimonate salt of an amine radical cation. It is a blue solid that reacts with many solvents but is soluble in acetonitrile . The compound is a popular oxidizing agent in organic and organometallic chemistry , with a reduction potential of 0.67 V versus ferrocene /ferrocenium ( acetonitrile ...
In a letter to Angewandte Chemie, the German chemist Manfred Christl [14] pointed out not only that the alleged new chemistry was in fact 100-year-old Zincke chemistry but also that the proposed structure for the reaction product was not the 12 membered ring but the 6 membered pyridinium salt (structure 2).
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral).
The salt hydrolyzes readily: [Me 3 O] + [BF 4 ] − + H 2 O → Me 2 O + MeOH + H + [BF 4 ] − Trimethyloxonium tetrafluoroborate is generally ranked as the strongest commercially available reagent for electrophilic methylation , [ 1 ] being stronger than methyl sulfonate esters, including methyl triflate and methyl fluorosulfonate ("magic ...
The trimethyloxonium salt is available from dimethyl ether via an analogous route. [6] These salts do not have long shelf-lives at room temperature. They degrade by hydrolysis: [Et 3 O] + [BF 4] − + H 2 O → Et 2 O + EtOH + H + [BF 4] −. The propensity of trialkyloxonium salts for alkyl-exchange can be advantageous.
The weight of the salt byproduct is greater than the weight of the amine. [12] In the laboratory, the Ritter reaction suffers from the necessity of an extremely strong acid catalyst. Other methods have been proposed in order to promote carbocation formation, including photocatalytic electron transfer [17] or direct photolysis. [18]
Sodium hydrogenoxalate or sodium hydrogen oxalate is a chemical compound with the chemical formula NaHC 2 O 4.It is an ionic compound.It is a sodium salt of oxalic acid H 2 C 2 O 4.It is an acidic salt, because it consists of sodium cations Na + and hydrogen oxalate anions HC 2 O − 4 or HO−C(=O)−CO − 2, in which only one acidic hydrogen atom in oxalic acid is replaced by sodium atom.
