Abstract

Abstract A rigorous procedure was developed for measuring the relative rates of addition of bromine atoms to eleven substituted α-methylstyrenes (1-Y, with Y= CF 3, NO 2, F, CN, Cl, Br, CO 2 Me, Me, COMe, OMe and SMe). The reaction was run in tetrahydrofuran in the presence of HBr, O 2 and dibutyl peroxyoxalate at 30 C. All products were derived from the YC 6 H 4 CMeCH 2 Br adduct radicals, which were immediately intercepted by O 2. ...
