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.
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.
In August 2020, the U.S. Food and Drug Administration (FDA) became aware of nitrosamine impurities in certain samples of rifampin. [61] The FDA and manufacturers are investigating the origin of these impurities in rifampin, and the agency is developing testing methods for regulators and industry to detect the 1-methyl-4-nitrosopiperazine (MNP ...
In principle, salt metathesis reactions can adjoin an allyl ligand from an allylmagnesium bromide or related allyl lithium reagent. [3] However, the carbanion salt precursors require careful synthesis, as allyl halides readily undergo Wurtz coupling. Mercury and tin allyl halides appear to avoid this side-reaction. [12]
The compound is prepared by the salt metathesis reaction of potassium iodide and potassium tetrachloroplatinate: [3] K 2 PtCl 4 + 4 KI → K 2 PtI 4 + 4 KCl. Potassium tetraiodoplatinate is a precursor to the anticancer drug cisplatin.

Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt with a bromide commonly used as a phase transfer catalyst. [4] It is used to prepare many other tetrabutylammonium salts by salt metathesis reactions. The anhydrous form is a white solid. [2]
The distinctive feature of the Grignard reagents is their formation from the organic halide and magnesium metal. Most other group II organic compounds are generated by salt metathesis, which limits their accessibility. The formation of the Grignard reagents has received intense scrutiny.
