Cycloaddition reactions of cyclopentadienylirondicarbonyl 2-alkynyl complexes (1) with diphenyl ketene (2) yields transition-metal substituted cyclopentenones (4). The transition metals can subsequently be cleaved from the cyclopentenones under a variety of oxidative and nonoxidative reaction conditions.

Reactions of cyclopentadienyl iron 2-alkynyl and allyl complexes with ketenes or ketene precursors yield transition-metal substituted cyclopentenones in some cases and new transition-metal substituted allyl complexes in others. The transition metals can subsequently be cleaved from the cyclopentenone containing complexes under a variety of oxidative and nonoxidative reaction conditions.
