title: New stable neutral radical with intramolecular hydrogen bonding: synthesis and characterization of 2,5,8-tri-tert-butyl-7-hydroxy-6-oxophenalenoxyl.
abstract: A new stable neutral radical with intramolecular hydrogen bonding, 2,5,8-tri-tert-butyl-7-hydroxy-6-oxophenalenoxyl, was synthesized from the corresponding dihydroxyphenalenone and isolated as a stable solid under air atmosphere at room temperature. The structure was unequivocally determined by means of IR spectra, ESR/ENDOR techniques, and DFT calculations.
