Organocatalysis is a type of chemical reaction that uses small organic molecules as catalysts to speed up reactions. Unlike traditional catalysts, which are often metals, organocatalysts are typically made from carbon-based compounds. This approach is valued for its simplicity, efficiency, and environmental friendliness, as it often requires milder reaction conditions and generates fewer byproducts. In organocatalysis, the organic molecules interact with the reactants to lower the energy barrier for the reaction, facilitating the transformation. This method has gained popularity in various fields, including pharmaceuticals and materials science, due to its versatility and ability to create complex molecules with high selectivity.
