One reviewer has indicated that this in-plane aromatic character may be related to the reactant-like nature of the transition structures included in this work. According to his opinion, it would be interesting to scrutinize also reactions with product-like transition structures. We agree with this appreciation, and we are currently investigating this kind of reactions, in which an aromatic ring is generated. These additional studies are underway in our laboratory and will be published separately.
