The synthesis of a dicyclopenta[a,e]pentalene via a molybdenum hexacarbonyl-mediated tandem allenic Pauson-Khand reaction.

Abstract

An approach to the 14pi annulene has been developed, by employing the molybdenum hexacarbonyl-mediated tandem allenic Pauson-Khand reaction as a key step. A di-triisopropylsilyl substituted dicyclopenta[a,e]pentalene was synthesized. This 14pi annulene showed some electronic delocalization, which was not observed in previous cases.
