Abstract:
Using EPR spectroscopy, β-fragmentation of the radicals PhCH2CH2ĊHX (R1, X = H; R2, X = CF3; R3, X = Me; R4 X = CO2Me) accompanied by C—C bond cleavage has been found and studied, and the activation energy of this reaction has been calculated, thus permitting us to determine the rate constants for fragmentation of R1 (k3a = 3.9( ± 0.2) × 104 s−1, R2 (k3b = 6.5( ± 0.4) × 103 s−1 and to evaluate the value of this rate constants for radical R3 and R4 (k3 = 102 s−1) at 22 °C.
