Abstract

Abstract: The cobalt‐catalyzed selective isomerization of terminal alkenes to the thermodynamically less‐stable (Z)‐2‐alkenes at ambient temperatures takes place by a new mechanism involving the transfer of a hydrogen atom from a Ph2 PH ligand to the starting material and the formation of a phosphenium complex, which recycles the Ph2 PH complex through a 1, 2‐H shift.
