Solubility
Silver Carbonate is soluble in water.
Solubility of a substance depends on the type of solvent and temperature. It is also influenced by the presence of other solutes in the solution.
In a saturated solution, the concentration of a solute will not increase with the addition of another solute.
Sodium carbonate reacts with silver nitrate to form Ag2CO3 (Silver salt). Solubility of this compound in nitric acid is 0.32g/L at room temperature.
The chemical formula of this salt is Ag2CO3. It has a density of 6.077gm/cm3 and melting point of 218degC.
Synthesis of Pyrroles and Indolizines
In 2014, Bi and co-workers reported the synthesis of pyrroles and indolizines from cyclization of 2-pyridyl alkynyl carbinols 16 with isocyanides (Scheme 11) [26]. This Ag-catalyzed reaction afforded tertiary propargyl alcohols 17a by a regioselective [3+2] cycloaddition. This method can be used to synthesize a wide range of tertiary propargyl compounds such as pyrroles, indolizines, furans, and nitriles.
C-H Amination of 2-alkenylanilines 69
In 2015, the Youn group reported the synthesis of diverse substituted indoles 70 from a C-H amination of 2-alkenylanilines (Scheme 42) [59]. The indole products containing R1 on the 2-position were selectively obtained when DMFA was employed as the solvent.
Besides its general use as an oxidant, silver carbonate can be applied as an inorganic base in palladium-catalyzed C-H activations in organic solvents with acidic protons. It is particularly useful for acyl radical formation from carboxylic acids, terminal alkynes, and 1,3-dicarbonyl compounds.
