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.
环戊二烯基2-炔基铁和烯丙基配合物与乙烯酮或乙烯酮前体的反应在某些情况下会生成过渡金属取代的环戊烯酮,在其他情况下会生成新的过渡金属取代的烯丙基配合物。随后可以在各种氧化和非氧化反应条件下,将过渡金属从含环戊烯酮的配合物中裂解。
