The relative rates of radical chlorination of m- and p- substituted benzaldehydes with sulphuryl chloride at 40° in CCl4 have been determined by means of a competitive reaction using p-diethylbenzene as reference standard. The relative reactivities were calculated from the amounts of aroyl chloride and α-chloro-p-diethylbenzene found and a polar effect (ρ{variant} = -0·53) was shown to be correlated by the Hammett equation with the σ constants. A comparison of the ρ{variant}-values with the redetermined value (ρ{variant} = -1·13) at the same temperature for bromotrichloromethane with the same system shows that radical halogenation with SO2Cl2 is much less selective than with BrCCl3. © 1970.
