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 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 methyl ...
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.
Sodium hexametaphosphate is the alkali salt of one of the series of polymetaphosphoric acids (acids formed by the polymerization of phosphate groups). [14] Hexametaphosphoric acid was first made in 1825 by the German chemist Johann Frederich Philipp Engelhart (1797-1853). [ 15 ]
WASHINGTON (Reuters) -U.S. unit labor costs grew far less than initially thought in the third quarter, pointing to a still favorable inflation outlook even though price increases have not ...
Potassium thioacetate is an organosulfur compound and a salt with the formula CH 3 COS − K +. This white, water-soluble solid is used as a reagent for preparing thioacetate esters and other derivatives.
