Abstract

Using EPR spectroscopy, the rate constants for the addition of radicals CC13(CH2· CH2)n, (R1 for n=1 and R2 for n=2), CCl3CH2CHCH3 (R3), and CCl3CH2CHCl (R4) to unsaturated compounds CH2=CHX (X=C6H5, COOCH3, CN) and CH2=C(CH3)Y (Y=C6H5, COOCH3) at 22‡C have been determined. The radicals R1 and R2 exhibit ambiphilic, and R4 electrophilic character towards the selected unsaturated compounds. It has been shown that the presence of the CCl3 group in the 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.
