regioselectivities
Regioselectivity refers to the preference of a chemical reaction to occur at one specific constitutional isomer of a reactant over others. In organic chemistry, this phenomenon is crucial when a reactant has multiple sites where a reaction could potentially take place. For instance, if a molecule possesses two different carbon atoms that can undergo addition, regioselectivity dictates which of these positions the incoming reagent will preferentially attach to.
This preference arises from differences in the stability of intermediate species, such as carbocations or carbanions,
Understanding and controlling regioselectivity is essential for synthetic chemists aiming to produce specific desired products with
