Do Antarafacial Cycloadditions Occur? Cycloaddition of Heptafulvalene with Tetracyanoethylene
Chemistry – A European Journal, 2022AbstractThe cycloaddition of heptafulvalene (1) with tetracyanoethylene (TCNE) was previously described as an example of an antarafacial cycloaddition, a [π14a+π2s] process that afforded only the trans cycloadduct by virtue of the edge‐to‐face approach of TCNE, facilitated by the S shape of 1.

Dynamics of Carbene Cycloadditions
Journal of the American Chemical Society, 2011Quasiclassical trajectory calculations using quantum mechanical energies and forces generated by the Venus and Gaussian programs provide for the first time a detailed dynamical picture of singlet carbene, CCl(2) and CF(2), cycloadditions to alkenes on the B3LYP/6-31G* surface.

Die thermische [2+2]Cycloaddition von Alkenen 1 ist nach den Woodward-Hoffmann-Regeln 1) suprafacial symmetrieverboten und kann nur in speziellen Fallen erfolgreich durchgefuhrt werden. Hingegen ist das photochemische Pendant erlaubt und wird als praparativ wertvolle Methode zur Bildung von Vierringsystemen 2 vielfaltig genutzt.2–4)
