The Diels–Alder reaction leads to a mixture of two diastereomers, one called endo and the
other one exo. The cyclo-reversion temperature of the first one is lower than the exo adduct …

The participation of different diaryldiazomethanes as three-atom components (TACs) in [3+
2] cycloaddition reactions with (E)-3, 3, 3-trichloro-1-nitroprop-1-ene was analysed. All of the …

The dependence of cycloaddition rate constants on solvent polarity is a significant
mechanistic criterion. Various model reactions are discussed. The slow step of the 2+ 2 …

DFT calculations were performed to shed light on the molecular mechanism of [3+ 2]
cycloadditions of simple conjugated nitroalkenes to benzonitrile N-oxides. In particular, it …

DFT calculation results shed a new light on the mechanism of cycloaddition reaction
between tetrafluoroethene and cyclopentadiene. The unique influence of fluorine atoms on …

The mechanistic aspects of the hetero Diels–Alder reactions between strongly electrophilic
(E)-2-aryl-1-cyano-1-nitroethenes and ethyl vinyl ether have been analyzed on the basis of …

Abstract The Diels–Alder reaction of β-fluoro-β-nitrostyrenes with cyclic 1, 3-dienes was
investigated. A series of novel monofluorinated norbornenes was prepared in up to 97 …

The Diels‐Alder reaction of β‐fluoro‐β nitrostyrenes with some linear dienes was
investigated. A number of monofluorinated [4+ 2]‐cycloadducts was prepared in up to 90 …

A migration of the nitro group in the trifluoromethylated partially hydrogenated dibenzopyran
system was studied using various DFT theoretical levels. It was found that this reaction …
