Salt metathesis is a common technique for exchanging counterions. The choice of reactants is guided by a solubility chart or lattice energy. HSAB theory can also be used to predict the products of a metathesis reaction. Salt metathesis is often employed to obtain salts that are soluble in organic solvents.
Historically, there have been two main approaches to prepare tetramethylammonium fluoride: hydrofluoric acid neutralization of tetramethylammonium hydroxide, and salt metathesis between different ammonium salts and inorganic fluoride sources, such as KF or CsF. [1]
Ammonium perchlorate (AP) is produced by reaction between ammonia and perchloric acid.This process is the main outlet for the industrial production of perchloric acid.The salt also can be produced by salt metathesis reaction of ammonium salts with sodium perchlorate.
The reaction is driven by the low solubility of potassium chlorate in water. The equilibrium of the reaction is shifted to the right hand side by the continuous precipitation of the product (Le Chatelier's Principle). The precursor sodium chlorate is produced industrially in very large quantities by electrolysis of sodium chloride, common table ...
It is prepared from tetraethylammonium bromide by salt metathesis, using a hydroxide-loaded ion exchange column or by the action of silver oxide. [3] Attempted isolation of Et 4 NOH induces Hofmann elimination, leading to triethylamine and ethylene. Treatment of Et 4 NOH with a wide range of acids gives water and the other tetraethylammonium salts:
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.
Tributyltin azide is synthesized by the salt metathesis reaction of tributyltin chloride and sodium azide. It is a reagent used in the synthesis of tetrazoles, which in turn are used to generate angiotensin II receptor antagonists. In some applications, tributyltin azide has been replaced by the less toxic trioctyltin azide and organoaluminium ...
RC≡W(O-t-Bu) 3 can react with normal alkynes for metathesis reactions and also with terminal alkynes for both metathesis reactions and polymerizations. [ 6 ] Besides simple metathesis reactions, W 2 (O- t -Bu) 6 also reacts with 3-hexyne in a 1:1 molar ratio to form a triangular tritungsten complex compound [W 3 (O- t -Bu) 5 (μ-O)(μ-CEt)O ...
