ABSTRACT

Efficient methodology for the functionalization of the exocyclic double bond in tricarbonyl [(l-4-η)-2-methoxy-5-methylenecyclohexa-l,3-diene] iron 7, has been established by employing the following procedure: (i) sequential electrophilic- nucleophilic addition; (ii) radical addition; and (iii) cycloaddition reaction. The Fe(CO)₃-moiety plays an important role in controlling the inherent chemo-, regio- and stereoselectivity during the reactions.
