Reactive intermediates in the photolysis of cyclopentadienylcobalt(I) dicarbonyl and in the reduction of cyclopentadienylcobalt(III) carbonyl diiodide 2013-07-15T06:29:32Z 1977 2013-07-15T06:29:32Z Brintzinger, Hans-Herbert terms-of-use Lee, Wai-Sun Photolysis of (C<sub>5</sub>H<sub>5</sub>)Co(CO)<sub>2</sub>(I) in toluene or petroleum ether solution at −78°C generates the unsaturated monocarbonyl species (C<sub>5</sub>H<sub>5</sub>)Co(CO), which was identified in solution by its IR spectrum. At room temperature, this monocarbonyl can associate with excess I to give (C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>Co<sub>2</sub>(CO)<sub>3</sub>, or dimerize to (C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>Co<sub>2</sub>(CO)<sub>2</sub>. The latter is stable as a solid, but in solution it is slowly converted to the insoluble trimer (C<sub>5</sub>H<sub>5</sub>)<sub>3</sub>Co<sub>3</sub>(CO)<sub>3</sub>. (C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>Co<sub>2</sub>(CO)<sub>2</sub> is symmetrically cleaved by phosphines to (C<sub>5</sub>H<sub>5</sub>)Co(CO)(PR<sub>3</sub>), while diolefins bring about unsymmetrical cleavage to give (C<sub>5</sub>H<sub>5</sub>)Co(diolefin) and (C<sub>5</sub>H<sub>5</sub>)Co(CO)<sub>2</sub>.
