How is salt metathesis conducted in a nonaqueous solution?

Salt metathesis can be conducted in nonaqueous solution, illustrated by the conversion of ferrocenium tetrafluoroborate to a more lipophilic salt containing the tetrakis (pentafluorophenyl)borate anion: When the reaction is conducted in dichloromethane, the salt NaBF 4 precipitates and the B (C 6 F 5) 4 - salt remains in solution.

What is the general scheme of salt metathesis?

This reaction is represented by the general scheme: The bond between the reacting species can be either ionic or covalent. Classically, these reactions result in the precipitation of one product.

How are metal complexes alkylated in Salt metathesis?

Metal complexes are alkylated via salt metathesis reactions. Illustrative is the methylation of titanocene dichloride to give the Petasis reagent: The salt product typically precipitates from the reaction solvent. A neutralization reaction is a type of double replacement reaction.

Which is an example of a metathesis reaction?

Neutralization occurs when equal amounts of acid react with equal amounts of a base. A neutralization reaction creates a solution of salt and water, for example: Metathesis reactions can occur between two inorganic salts when one product is insoluble in water, driving the reaction forward, as in the following examples:
