Nonoxidative Transient-Metal-Carbon Bond Cleaving Reactions and Their Application in a Transition-Metal Mediated Cyclopentenone Synthesis.

, p. 177 - 180 (1992)
Cycloaddition reactions of cyclopentadienyl iron dicarbonyl 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 transition-metal η1-allyl and propargyl complexes with ketenes and some new nonoxidative transition-metal-carbon bond cleaving reactions of the ketene cycloadducts which yield cyclopentenones

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.
