Coinage metal catalysis has become a potent tool for a variety of C-C and C-X bond formation events, frequently with intriguing molecular routes. Catalysts made of coinage metal can be used alone or in combination with other catalysts. The synthesis of heterocyclic compounds can be catalyzed by coinage metals like copper, silver, and gold. The literature contains a variety of well-established methods for synthesizing heterocycles, which has been a research objective for over a century. A new approach to synthesizing knowledge has been developed over the past few years through efficient and atom-economic routes. One of the most appealing features of the many recently developed synthetic transformations is transition metal-catalyzed reactions. In mild conditions, complex molecules can be created directly from readily available starting materials through these reactions. This section focuses on the uses of heterocycles created using coinage metal catalysis in the fields of materials science, medicine, and agrochemicals. These heterocyclic compounds' exceptional biological activity and distinctive characteristics have led to their usage in advanced material development, medicine research, and crop protection. Modern organic chemistry has been revolutionized by the use of coinage metals as catalysts in heterocycle synthesis, which allows the creation of complex structures with extraordinary efficiency and accuracy.
