Several alternatives to mCPBA exist, each with its own set of advantages and disadvantages: 1. Hydrogen Peroxide: Often used in conjunction with catalysts, hydrogen peroxide is a more cost-effective and environmentally friendly oxidizing agent. 2. Sodium Periodate: This reagent is less expensive and more stable but may lack the selectivity of mCPBA. 3. Oxone: A commercially available triple salt (potassium peroxymonosulfate) that serves as a powerful oxidizing agent, often used as an alternative to mCPBA.
