“…As described for almost every telomerisation 1:1adducts of diene and nucleophile, in this case phenoxybutenes (3,4) and butenylphenols, e.g. (6), and a linear dimer of butadiene, 1,3,7-octatriene (7), are also formed as by-products. Smutny discovered this reaction while working on oligomerisations of butadiene.…”
