説明
4-Hydroxy-3H-cyclopent[a]azulen-3-one, a new tricyclic π-conjugated system containing a hydroxyazulene unit and a cyclopentadienone moiety, was synthesized by the application of flash vacuum pyrolysis in the final step. All the proton magnetic resonances of the compound shifted up-field compared with those of the referenced 1,2-dihydro compound in terms of an induced paramagnetic ring current in the periphery of this molecule. The characteristic prototropic tautomerization of 4-hydroxyazulenes was not observed in this system.
