Unusual Structure-Energy Correlations in Intramolecular Diels–Alder Reaction Transition States [PDF]
Molecules, 2014 Detailed analysis of calculated data from an experimental/computational study of intramolecular furan Diels–Alder reactions has led to the unusual discovery that the mean contraction of the newly forming C-C σ-bonds from the transition state to the ...
