The reactivities of β-methylstyrenes differ for the Z and E isomers (see Table 5).In hydration and bromination the relative reactivities are similar. 221, 222 The much higher rate constant in the addition of benzhydryl cation to the E isomer than to the Z isomer may suggest the preliminary coordination of the carbenium ion with a phenyl substituent prior to the addition. 223 In the Z isomer .
