Unpredictable cycloisomerization of 1,11-dien-6-ynes by a common cobalt catalyst

1,11-Dien-6-ynes undergo cycloisomerization in the presence of the cobalt catalytic system CoBr(2)/phosphine ligand/Zn/ZnI(2) giving cyclohexene, diene or cyclopropane structures depending on the type of the phosphine ligand. This unpredictable behaviour suggests that, although the availability of t...

Descripción
Sumario:1,11-Dien-6-ynes undergo cycloisomerization in the presence of the cobalt catalytic system CoBr(2)/phosphine ligand/Zn/ZnI(2) 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.
