My watch list  


In chemistry, regioselectivity is the preference of one direction of chemical bond making or breaking over all other possible directions [1]. It can often apply to which of many possible position a reagent will affect, such as which proton a strong base will abstract from an organic molecule, or where on a substituted benzene ring a further substituent will add.

Regioselectivity in ring-closure reactions is governed by the Baldwin's rules.
