WebThe products of the reaction are the well characterised monoperoxoborate species and the parent carboxylic acid. Analysis of the pH and borate dependence data reveals that in addition to a catalytic pathway involving a single boric acid molecule, there is a significant pathway involving either (a) two boric acid molecules or (b) the polyborate species, B 3 O … WebThis accounts for the observed regiochemical outcome. Like in other S N 2 reactions, nucleophilic attack takes place from the backside, resulting in inversion at the electrophilic carbon. Probably the best way to depict the acid-catalyzed epoxide ring-opening reaction is as a hybrid, or cross, between an S N 2 and S N 1 mechanism.
