Encyclopedia > Alkoxide ion

An alkoxide has an organic group bonded to a negatively charged oxygen atom, they are generally basic. Alkoxides, though generally not stable, are found as intermediaries in various reactions, including the Williamson ether synthesis reaction for forming ethers.

Generation of alkoxide anions from a series of aliphatic diols and alcohols and their ion-molecule reactions with ... (257 words)
Alkoxide anions, [M – H] from a series of aliphatic diols and alcohols are generated in the source under negative ion electrospray ionisation conditions by cone-voltage fragmentation of the corresponding [M + F] ions.
ions among the series of diols varies as a function of chain length that could be explained based on their stabilities through intramolecular hydrogen bonding.
The reactivity of alkoxide anions is studied through ion–molecule reactions with CO in the collision cell of a triple quadrupole mass spectrometer.
Stability of sulfadiazine oral liquids prepared from tablets and powder. (1588 words)
The transesterification is a reversible reaction and its equilibrium depends on the relative concentrations and nucleophilic abilities of the alkoxide ions (11).
The basicity of the nucleophile is a dominant factor governing the relative reactivities of ester and alkoxide ions when the electrophilic center of the substrate is carbon of the carbonyl group (i.e., a hard Lewis acid).
The tert-butoxide ion has the most steric hindrance among these alkoxide ions, thus the rate of transesterification with tert-butanol is expected to be lower than the other reactions.
