Beryllium chloride is an inorganic compound with the formula BeCl 2. It is a colourless, hygroscopic solid that dissolves well in many polar solvents. Its properties are similar to those of aluminium chloride , due to beryllium 's diagonal relationship with aluminium .
Organoberyllium compounds are typically prepared by transmetallation or alkylation of beryllium chloride. [10] Beryllocene ... + BeCl 2 → [Cp] 2 Be + 2 KCl.
Like magnesocene, beryllocene also forms ferrocene with iron(II) chloride. [2] The driving force is the formation of the very stable ferrocene molecule. Be(C 5 H 5) 2 + FeCl 2 → BeCl 2 + Fe(C 5 H 5) 2. It is predicted to react with beryllium to generate C 5 H 5 BeBeC 5 H 5. [9]
Friedrich Wöhler [70] and Antoine Bussy [71] independently isolated beryllium in 1828 by the chemical reaction of metallic potassium with beryllium chloride, as follows: BeCl 2 + 2 K → 2 KCl + Be. Using an alcohol lamp, Wöhler heated alternating layers of beryllium chloride and potassium in a wired-shut platinum crucible.

A chloride ion is a structural component of some proteins; for example, it is present in the amylase enzyme. For these roles, chloride is one of the essential dietary mineral (listed by its element name chlorine). Serum chloride levels are mainly regulated by the kidneys through a variety of transporters that are present along the nephron. [19]
The straw-colored adduct Be(NO 3) 2 (N 2 O 4) forms upon treatment of beryllium chloride with dinitrogen tetroxide: . BeCl 2 + 3 N 2 O 4 → Be(NO 3) 2 (N 2 O 4) + 2 NOCl. Upon heating, this adduct loses N 2 O 4 and produces colorless Be(NO 3) 2.
Rubidium chloride is the chemical compound with the formula RbCl. This alkali metal halide salt is composed of rubidium and chlorine , and finds diverse uses ranging from electrochemistry to molecular biology .
