Catalytic bond functionalization through sustainable and energy-efficient synthetic methods Traditional bond functionalization depends on thermal activation and excess reagents, creating significant energy demands. Sustainable Approaches for Catalytic Bond Functionalization presents green strategies for functionalizing C?H, C?X (where X equals heteroatom), and C?C bonds that reduce energy consumption while maintaining synthetic efficiency across multiple compound classes. The book covers the application of photoelectrochemical, visible-light-induced and electrochemical pathways to the construction of complex organic molecules, natural products, active pharmaceutical ingredients, polymers, and advanced materials. Readers will also find: Practical insights into flow chemistry approaches in catalytic bond forming transformations Coverage of mechanochemistry and ball milling techniques as solvent-free alternatives A dedicated chapter on industrial applications connecting laboratory-scale methods to real-world challenges Designed for organic chemists, catalytic chemists, and chemical industry professionals, this book provides actionable methods for adopting sustainable bond functionalization in research and industry.
