| Abstract: | The cyclotrimerization reaction of benzobarrelene derivatives was investigated. Dibromobenzobarrelene 10 was converted to the bromostannyl derivative 11 , which was used as the substrate of the cyclotrimerization reaction. Thus, reaction of 11 , with copper(I) thiophene‐2‐carboxylate (CuTC) gave a mixture of the isomeric cyclotrimers 5 and 6 and the dimers 12 and 13 , in addition to a trace of protodestannylated bromoalkene 14 (Scheme 2). |
