| Abstract: | The rate constants for the reaction of the TEMPO radical with fluorene, 2-cyanofluorene, and 9-cyanofluorene were determined
by ESR. A comparison was made of the reactivity of the hydrocarbons in reaction with the TEMPO radical and the peroxyl radical.
The quantum-chemical characteristics of the radicals and particles taking part in the reactions and also the characteristics
of the transition states in the reactions of the TEMPO radical and cumenylperoxyl radical with fluorene were obtained by the
PM3 method.
