Do Antarafacial Cycloadditions Occur? Cycloaddition of Heptafulvalene with Tetracyanoethylene

Chemistry – A European Journal, 2022
AbstractThe 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.

Cycloadditions with Metauo-Phosphaalkenes

Phosphorus, Sulfur, and Silicon and the Related Elements, 1994
Abstract Cycloadditions of metallo-phosphaalkenes such as (C5Me5)(C0)2Fe− P=CR1R2 (R1 = R2 = SiMe3, NMe2; R1 = Ph, R2 = SiMe3) are performed with isocyanides, electron-poor alkenes, alkynes and heteroal ...

Dynamics of Carbene Cycloadditions

Journal of the American Chemical Society, 2011
Quasiclassical 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.

[2+2]Cycloaddition

1994
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)
