✦ Synopsis

Abstract

The three‐dimensional structure of the title compound has been established by means of an X‐ray analysis. The product was formed by a thermal 1,3‐dipolar cycloaddition. According to the concerted [~π~4~s~ + ~π~2~s~]‐mechanism the formation of this stereoisomer should actually be forbidden. The structure determined by X‐ray analysis confirms the chemical results.
