Abstract

The generation of bis-cyclopentadienones joined by a tether results in the stereoselective, intramolecular dimerization of these reactive intermediates. This cycloaddition leads to structures of high molecular complexity from relatively simple starting materials.

A rigorous temperature study will be performed when we have a clean cyclopentadienone precursor in hand.
