Reactions and Derived Synthetic Applications of Alkylidynetricobalt Nonacarbonyl Complexes

DECOMPOSITION REACTIONS AND DERIVED SYNTHETIC APPLICATIONS OF ALKYLIDYNETRICOBALT NONACARBONYL COMPLEXES 

This reaction has potential for useful application in organic synthesis. Oxidation of alkylidynetricobalt nonacarbonyl complexes with halogens was the key reaction that led Kriierke and Hubei to the correct assignment of their structure (3a)  

The action of iodine also causes nearly quantitative release of carbon monoxide from such complexes, but the organic triiodides presumably produced were not isolated (7). 

A few other reactions of those cluster complexes in which the RC fragment is converted to organic products have been reported and are summarized as follows
