Synthesis of organic molecules from functionalized alkynes and metal carbonyls. Reaction pathways and intermediates. Crystal structure of Fe3(CO)6(?-CO)2[(HC ? CCMe2)2NH

Abstract

The reactions of VIII Group metal carbonyls with dipropargylamines and other functionalized alkynes lead to new cluster and binuclear compounds: the ruthenium cluster derivatives may be considered as “models of intermediates” proposed in metal-mediated organic syntheses. The iron and cobalt carbonyls give metallacyclic derivatives which are intermediates in organic syntheses. The structure of Fe3(CO)6(μ-CO)2[(HC ≡ CCMe2)2NH] has been determined by an X-ray diffraction study.
