The allylic 1-methyl-3-bromobicyclo[3.2.1]octenyl exo-2 and exo-4 alcohols were treated with thionyl chloride in ether or pentane solution at 0°. In each case, a 50/50 mixture of exo allylic chlorides was obtained. No evidence for a predominant S_Ni'′reaction was detected; reported cases of such S_Ni'′ processes using these conditions should therefore be treated with reserve.
