Uses
Silver benzoate is an aromatic salt that is used as a catalyst to prepare β-amino acids (such as N-Acetyl-β-alanine) from α-amino acids (such as D-Alanine). Silver benzoate is also used as a catalyst in Wolff rearrangement reactions.
Application
Silver benzoate was used in the synthesis of triphenyltinbenzoate. It is an efficient catalytic system for the reaction of carbon dioxide with various ketones.
Reactions
Silver benzoate reacts with bromine in CCl4 refluxing to form C6H5Br This reaction is called Hunsdiecker reaction.
General Description
Silver benzoate along with 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTBD) is an efficient catalytic system for the reaction of carbon dioxide with various ketones.
Synthesis
Silver benzoate can be obtained by reacting silver nitrate and sodium benzoate:
AgNO3 + PhCOONa → PhCOOAg↓ + NaNO3
Reaction: Mix an equimolar amount of silver nitrate solution with sodium benzoate solution to precipitate silver benzoate. Washed with water and dried in a vacuum desiccator.
