摘要：

A series of complexes containing the novel σ-bonded allenyl ligand has been prepared from iridium(I), platinum(0), and cobalt(I) compounds. The complexes were formed by SN2′ attack on substituted 3-halopropynes. Provisional structures have been assigned to these complexes on the basis of their infrared, Raman, and nmr spectra. Kinetic evidence is presented demonstrating the second-order nature of the reaction. The reductive cleavage of the metal-carbon bond in the cobalt complexes, yielding alienes and the, regenerated cobalt(I) species, has been demonstrated. © 1969, American Chemical Society.
