Using EPR spectroscopy, the rate constants for the addition of radicals CCl3(CH2-CH2).n (R1 for n=1 and R2 for n=2), CCl3CH2CH.CH3 (R3), and CCl3CH2C.HCl (R4) to unsaturated compounds CH2=CHX (X=C6H5, COOCH3, CN) and CH2=C(CH3)Y (Y=C6H5, COOCH3) at 22 deg C have been determined.The radicals R1 and R2 exhibit ampiphilic, and R4 electrophilic character towards the selected unsaturated compounds.It has been shown that the presence of the CCl3 group in γ-position of the radical center has little effect on the reactivity of the radical.Replacement of a hydrogen on the α-carbon in radical R1 by a CH3 group or chlorine atom leads to a considerable reduction in the rate of addition of the radicals to the unsaturated compounds examined.
