aktivointireagenssit
Aktivointireagenssit, or activation reagents, are chemicals or small molecules used in organic synthesis to prepare functional groups for subsequent reactions. Their primary role is to convert relatively inert substrates into more reactive species, thereby facilitating transformations such as nucleophilic substitutions, coupling reactions, or radical processes. Activation often improves reaction rates, yields, and selectivity by lowering activation energies or enabling the use of milder conditions.
Typical activation reagents include carbodiimides (like dicyclohexylcarbodiimide, DCC), which activate carboxylic acids to form O‑acylureas that
Industrial applications of activation reagents span fine chemicals, pharmaceuticals, and materials science. In drug discovery, they
