Silver carbonate

Silver carbonate can be prepared by combining aqueous solutions of sodium carbonate with a deficiency of silver nitrate. With hydrofluoric acid, it gives silver fluoride. The thermal conversion of silver carbonate to silver metal proceeds via formation of silver oxide: : : ==Uses==

The principal use of silver carbonate is for the production of silver powder for use in microelectronics. It is reduced with formaldehyde, producing silver free of alkali metals: : Organic synthesis Silver carbonate is used as a reagent in organic synthesis. In the Fétizon oxidation, silver carbonate on Celite serves as an oxidising agent to form: • aldehydes from primary alcohols, • ketones from secondary alcohols, • keto-alcohols from diols, • and ketones from hydroxymethyl compounds. In the Koenigs-Knorr reaction it is used to convert alkyl bromides to the methyl ethers. It is also employed to convert alkyl bromides into alcohols. As a base, it has been used in the Wittig reaction. and in C-H bond activation. ==References==
