The halogen‐lithium interconversion reaction between p ‐bromophenyl‐cyclohexene‐1 and organolithium compounds was investigated. It resulted in the production of p ‐Δ 1 ‐cyclohexenyl‐phenyllithium. The organolithium compounds used in the interconversion reaction were phenyllithium, n ‐propyllithium and n ‐butyllithium. They brought about 25%, 19% and 10% conversions based on p ‐bromophenylcyclohexene‐1 respectively.
