| Abstract: | Among the various chloromethanes and chloroethanes, only compounds of the type R-CCl3 are reactive telogens for styrene in catalysed telomerizations of the type due to Vofsi. We have found evidence for a new type of breakdown of CCl3Br to CCI2Br and CI in addition to the known breakdown to CC13 and Br'. A Hammet equation has been established for the telomerization involving styrene and telogens of the type RCCl3. Excellent correlation has been found between the logarithm of the reactivity of a telogen and the Taft constant of the group R. |
