Potassium osmate is the inorganic compound with the formula K 2 [OsO 2 (OH) 4]. This diamagnetic purple salt contains osmium in the VI (6+) oxidation state. [1] When dissolved in water a red solution is formed. When dissolved in ethanol, the salt gives a pink solution, and it gives a blue solution when dissolved in methanol. [1]
Triethyloxonium tetrafluoroborate is the organic oxonium compound with the formula [(CH 3 CH 2) 3 O] + [BF 4] −. It is often called Meerwein's reagent or Meerwein's salt after its discoverer Hans Meerwein. [2] [3] Also well known and commercially available is the related trimethyloxonium tetrafluoroborate. The compounds are white solids that ...
4 Me 2 O·BF 3 + 2 Me 2 O + 3 C 2 H 3 OCH 2 Cl → 3 [Me 3 O] + [BF 4] − + B[(OCH(CH 2 Cl)CH 2 OMe] 3. 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 ...
The first reaction is the formation of the N-2,4-dinitrophenyl-pyridinium salt (2). This salt is typically isolated and purified by recrystallization. The formation of the DNP-pyridinium salt. Upon heating a primary amine with the N-2,4-dinitrophenyl-pyridinium salt (2), the addition
Potassium nonahydridorhenate(VII) is an inorganic compound having the formula K 2 [Re H 9].This colourless salt is soluble in water but only poorly soluble in most alcohols.This salt contains the nonahydridorhenate(VII) anion, [ReH 9] 2−, which is a rare example of a coordination complex bearing only hydride ligands.
Krogmann's salt was first synthesized by Klaus Krogmann in the late 1960s. [3] Krogmann's salt most commonly refers to a platinum metal complex of the formula K 2 [Pt(CN) 4 X 0.3] where X is usually bromine (or sometimes chlorine). Many other non-stoichiometric metal salts containing the anionic complex [Pt(CN) 4] n− can also be characterized.
"1923" will have its network premiere on Dec. 8 at 9 p.m. ET/PT and 8 p.m. CT on the Paramount Network.. The show will debut right after a new episode of "Yellowstone" Season 5, which airs at 8 p ...
The [BAr F 4] − anion with four fluorinated aryl groups distributed tetrahedrally about a central boron atom. Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups.
