Abstract
[GRAPHICS] A new stable neutral radical with intramolecular hydrogen bonding, 2,5,8-tr i-tert-butyl-7-hydroxy-6-oxophenalenoxyl, was synthesized from the correspo nding dihydroxyphenalenone and isolated as a stable solid under air atmosph ere at room temperature. The structure was unequivocally determined by mean s of IR spectra, ESR/ENDOR techniques, and DFT calculations.
