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.

Arene–Alkene Cycloaddition

Chemical Reviews, 2016
Cycloadditions are among the most efficient chemical processes, combining atom economy, stereospecificity, and the ability to generate molecular complexity in a single step. Aromatic rings would in principle be ideal reaction partners, as they contain, at least from the topological point of view, both olefinic and diene subunits; however, the stability
