Abstract The kinetics of metallotropy of the 3,6-di-tert-butyl-2-(triphenylstannyl)oxyphenoxyl radical has been studied by ESR. The correlation between chemical exchange time τex, solvent polarity, and longitudinal relaxation time of the solvent corresponds to the model of a process controlled by molecular dynamics. A linear relation between τex and correlation time τc for reorientation movements of the radical is found: τex = α · τc. The coefficient α depends on the dielectric properties of the solvent.
