Silver(I) oxide
Silver(I) oxide (CAS: 20667-12-3; Formula: Ag2O; Molar Mass: 231.74 g/mol) is a potent oxidizing agent used in organic synthesis. It is particularly effective for generating lactones from diols and mediating the monoprotection of symmetrical diols. Available as a powder or chunks with an assay of ≥99.99% trace metals basis, this compound is vital for advanced chemical research and materials science applications.
Lactone Synthesis
Silver(I) oxide serves as a crucial oxidizing agent for the efficient conversion of diols into lactones, a common structural motif in natural products and pharmaceuticals.
Selective Diol Monoprotection
This reagent facilitates the selective monoprotection of symmetrical diols using alkyl halides, yielding the desired protected intermediate with good to excellent yields in synthetic pathways.
Oxidizing Agent
As a strong oxidizing agent, Ag2O plays a key role in various chemical transformations within organic synthesis and inorganic chemistry.
