The electrophilic/nucleophilic character of a series of captodative (CD) ethylenes involved in
polar cycloaddition reactions has been studied using DFT methods at the B3LYP/6-31G (d) …

Details of the mechanism of asymmetric transfer hydrogenation of ketones catalyzed by two
chiral bifunctional ruthenium complexes,(S)-RuH [(R, R)-OCH (Ph) CH (Ph) NH2](η6 …

Concerted reactions are proposed to be keys to understanding thermal decomposition of
glucose in the absence of ionic chemistry, including molecular catalysis by ROH molecules …

1, 3-Cyclohexadiene ring opening has been studied within the bonding evolution theory
(BET) framework. We have focused on describing for the first time the electron pair …

The kinetic solvent effects on the 1, 3‐dipolar cycloaddition (13DC) of benzonitrile N‐oxide
with cyclopentene [T. Rispens and JBFN Engberts, J. Phys. Org. Chem. 2005; 18, 908–917] …

The electrophilic/nucleophilic behavior of dimethyl 2, 3-dimethylenesuccinate 1, an electron-
deficient 2, 3-disubstituted 1, 3-butadiene, in polar Diels− Alder reactions has been studied …

A triazolopyridinium salt chemodosimeter has been developed that displays a 60-fold
enhancement in fluorescence upon reaction with cyanide. The novel, fast, selective and …

Recent computational and experimental studies of organic reactions that show sequential
transition structures on the potential energy surfaces are reviewed. The specific focus is on …

Hydroxyl groups in the simple cyclic sugar β-d-glucose are key to its formation of bicyclic
levoglucosan, whether by unimolecular reaction or by catalysis through external hydroxyls …

The ongoing controversy whether cyclization reactions of conjugated allenes or ketenes
follow a pericyclic or a pseudopericyclic mechanism has triggered dozens of investigations …
