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. Illustrative is the conversion of sodium perrhenate to the tetrabutylammonium salt: [2] NaReO 4 + N(C 4 H 9) 4 Cl → N(C 4 H 9) 4 [ReO 4] + NaCl
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.
A white water-soluble solid, it is a quaternary ammonium salt of chloride. It sees use as a phase-transfer catalyst, although it is less popular that the corresponding bromine salt TBAC. It can also undergo salt metathesis reactions to form a variety of other tetrabutylammonium salts.
Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt with a bromide commonly used as a phase transfer catalyst. [5] It is used to prepare many other tetrabutylammonium salts by salt metathesis reactions. The anhydrous form is a white solid. [2]
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.
Metathesis (linguistics), alteration of the order of phonemes within a word Quantitative metathesis , exchange of long and short roles, without changing order of vowel sounds Chemical change in which a pair of molecules exchange electronic patterns of bonding
The Petasis reagent is prepared by the salt metathesis reaction of methylmagnesium chloride or methyllithium [2] with titanocene dichloride: [3] Cp 2 TiCl 2 + 2 CH 3 MgCl → Cp 2 Ti(CH 3) 2 + 2 MgCl 2. This compound is used for the transformation of carbonyl groups to terminal alkenes. It exhibits similar reactivity to the Tebbe reagent and ...
I wouldnt add it, although your observations are insightful. My reasoning: (1) salt metathesis is really intended for salt-like reagents, (2) Wikipedia guidelines urge us not to make it into a textbook. The encylopedia is intended to give and explain facts, but not to go much farther.
