This text offers experimental methods for a variety of organic reactions, organized by reaction type, and discusses the advantages and limitations of each procedure. Traditional methods to accelerate organic reactions often involve energy-intensive processes and environmentally harmful solvents, along with time-consuming purification steps for product isolation. A practical solution for reactions with anionic reactants is phase-transfer catalysis, where quaternary ammonium cations facilitate the transfer of anionic reactants as non-solvated ion-pairs from aqueous to organic media. This approach enhances the reactivity of anionic species and increases their encounter rate with organic substrates, often eliminating side reactions and improving overall product yield. The book presents procedures that reduce reaction times and the need for extreme conditions typically required in standard methods. As the only publication focused on quaternary ammonium salts, it serves as a valuable resource for synthetic chemists, allowing them to evaluate various alternatives and their respective advantages and limitations. Each volume in the Best Synthetic Methods series addresses specific topics from a practical standpoint, providing detailed examples and precise experimental guidance, making it an essential guide for modern synthetic organic chemistry.
