1,11-Dien-6-ynes undergo cycloisomerization in the presence of the cobalt catalytic system CoBr/phosphine ligand/Zn/ZnI giving cyclohexene, diene or cyclopropane structures depending on the type of the phosphine ligand. This unpredictable behaviour suggests that, although the availability of the cobalt catalytic system is appealing, the development of well-defined catalysts is desirable for further progress.

1,11-二烯-6-炔在钴催化体系CoBr/膦配体/Zn/ZnI存在下发生环异构化反应，根据膦配体的类型生成环己烯、二烯或环丙烷结构。这种不可预测的行为表明，尽管钴催化体系具有吸引力，但为了进一步取得进展，开发明确的催化剂是很有必要的。
