New stable oxophenalenoxyl: Preparation and characterization of a 4-oxophenalenoxyl derivative
A 4-oxophenalenoxyl derivative, 2,5,8-tri-tert-butyl-4-oxophenalenoxyl, was prepared for the first time. This radical was successfully isolated in solid state. Its electronic spin structure was unequivocally characterized by means of liquid-phase ESR, ENDOR/TRIPLE measurements and DFT calculations.
