Kinetics and mechanism of bromination of styrenes

The kinetics of bromination of six substituted styrnes (3-fluoro-, 3-chloro-, 3-bromo-, 3,4-dichloro-, 3-nitro-, and 4-nitro-) in anhydrous acetic acid have been investigated at several temperatures. At 25.3 C the reactions follow the rate expression The rate constants for the second order process show a good linear free energy relationship of the log k versus σ type with ρ = − 2.24.
