Anhydrous aluminium chloride is a powerful Lewis acid, capable of forming Lewis acid-base adducts with even weak Lewis bases such as benzophenone and mesitylene. [14] It forms tetrachloroaluminate ([AlCl 4] −) in the presence of chloride ions. Aluminium chloride reacts with calcium and magnesium hydrides in tetrahydrofuran forming ...
Lastly, a second Friedel-Crafts acylation takes place with addition of acid. [ 27 ] The product formed in this reaction is then analogously reduced, followed by a dehydrogenation reaction (with the reagent SeO 2 for example) to extend the aromatic ring system.
Anhydrous metal chlorides suitable for preparing other coordination compounds may be dehydrated by treatment with thionyl chloride: [1] [3] MCl n · x H 2 O + x SOCl 2 → MCl n + x SO 2 + 2 x HCl The silver and thallium(I) cations have a great affinity for halide anions in solution, and the metal halide quantitatively precipitates from aqueous ...
A body was found in the passenger seat of a vehicle after a driver was pulled over during a traffic stop in Georgia on the night of Wednesday, Jan. 29, police say.
The group of protesting fans also called for the team to be sold. The Mavericks are owned by the family of Miriam Adelson, who run the Las Vegas Sands casino company.
Evidence for inter- and intramolecular mechanisms have been obtained by crossover experiments with mixed reactants. [citation needed] The reaction progress is not dependent on solvent or substrate. A widely accepted mechanism involves a carbocation intermediate. The Fries rearrangement
Miles hit a stunning step-back three to highlight Notre Dame’s 20-0 run in the second quarter. Key stat. Notre Dame owned a 45-12 advantage in points off of turnovers. Up next.
Aluminium chlorohydrate is a group of water-soluble, [1] specific aluminium salts having the general formula Al n Cl 3n−m (O H) m.It is used in cosmetics as an antiperspirant and as a coagulant in water purification.
