Definition of Dianions. Meaning of Dianions. Synonyms of Dianions

- A dianion is an anion with a net charge of −2. While there exist many stable molecular dianions, such as BeF4 2− and MgF4 2−, thus far no stable atomic...
- the second-strongest, and the para isomer is the third-strongest. These dianions were generated in a linear quadrupole ion-trap m**** spectrometer. Electrospray...
- (2000). "Ab Initio Investigation of Electron Detachment in Dicarboxylate Dianions". The Journal of Physical Chemistry A. 104 (50): 11786–11795. Bibcode:2000JPCA...
- for the isolated [C4BH5]2− dianion as illustrated below. Since borole dianions are isoelectronic to the ubiquitous cyclopentadienyl anion, aromatic delocalisation...
- species with a formula of [C8H8]2− and abbreviated as COT2−. It is the dianion of cyclooctatetraene. Salts of the cyclooctatetraenide anion can be stable...
- The Ivanov reaction is the chemical reaction of the dianions (endiolates) of aryl acetic acids (Ivanov reagents) with electrophiles, primarily carbonyl...
- atom and one other element in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O2– ion with oxygen in...
- the production of sodium tetrasulfide: 4 Na + S8 → 2 Na2S4 Some of these dianions dissociate to give radical anions, such as S−3 gives the blue color of...
- in the alpha position next to the carboxylate group can be converted to dianions with strong bases like lithium diisopropylamide. These react with alkyl...
- the strongest known base until 2008, when the isomeric diethynylbenzene dianions were determined to have a higher proton affinity. The methanide ion CH−3...
