Abstract: | Many reports on the mass spectra of organotransition-metal complexes have appeared in recent years,1 whilst there have only been a few reports on the mass spectra of transition metal olefin complexes, some metal carbonyl olefin complexes234 and π-cyclooctenyl-π-cyclooctadienyl cobalt.5 Recently fragmentation paths of π-cyclopentadienyl-cyclooctadiene rhodium were elucidated by King.6 The present authors found metastable ions in the mass spectra of π-cyclopentadienyl-diene cobalt complexes as well as in the mass spectra of π-cyclopentadienyl-diene rhodium complexes.7. In the present paper the authors wish to report the mass spectra of several π-cyclopentadienyl diene cobalt complexes. |
