Application

Silver carbonate (Ag2CO3) is primarily used as a mild oxidizing agent in organic chemistry, facilitating the conversion of alcohols to aldehydes and ketones. It appears as a light yellow or yellow-green powder, which can darken upon light exposure and decomposes to silver oxide when heated, a process useful for creating other silver compounds. In addition to its role in oxidation reactions, silver carbonate is employed in biological staining and the Koenigs-Knorr glycosylation process. Although not a strong oxidizing agent, it effectively oxidizes alcohols to carbonyl derivatives, as demonstrated by Rapoport's oxidation of codeine to codeinone with a 75% yield, further enhanced in subsequent studies to 85% under varying conditions. Its application extends to the synthesis of complex molecules, such as 3-Oxo-12a-hydroxy-5β-cholanoic Acid, a keto bile acid derivative, using Silver Carbonate on Celite. Despite its limited solubility and reactivity, silver carbonate remains a vital reagent in chemical synthesis due to these versatile applications.
