摘要: Durch Bestimmung der Hydrierwarme wird fur das Bicyclo[6.2.0]decapentaen (1) eine Resonanzenergie von + 3.7 kcal/mol ermittelt. Dieser Befund steht im Widerspruch zu dem aufgrund theoretischen Betrachtungen erwarteten antiaromatischen Charakter 1. Heats of Hydrogenation, 61). Resonance Energy Fused [4n]Annulenes From heat hydrogenation measurements a resonance energy has been derived for bicyclo[6.2.0]decapentaene (1). This value is at variance with the antiaromatic character expected 1 from theoretical considerations.
