👉 In organic chemistry, a semicatalyst is a chemical substance that catalyzes a reaction without directly participating in it. It is often used as a catalyst to speed up the rate of certain reactions, although it does not directly change the overall product or reactant composition. Semicatalysis is an important concept in the field of organic chemistry and catalysis because it can significantly increase the efficiency and selectivity of chemical reactions. This type of catalysis is often used in the production of pharmaceutical
