Despite advances in the synthesis of polysubstituted cyclopentadienyl metal complexes, the rapid access to a library of monosubstituted Cp bearing metal complexes remains challenging. A convenient and general method to access a broad range of monosubstituted cyclopentadienyl rhodium(I) and iridium(I) complexes is reported. The process involves a direct nucleo-metalation of fulvenes with widely available metal precursors, affording a set of CpRh^I(olefin)₂ and CpIr^I(olefin)₂ complexes in high yields. A broad range of oxygen-, nitrogen-, and carbon-based nucleophiles were found competent for the process and offer good tuning abilities of the cyclopentadienyl portion.

通过同时的亲核加成金属化方法制得的单取代环戊二烯基铑（I）和铱（I）配合物。

尽管在多取代的环戊二烯基金属配合物的合成方面取得了进展，但是快速获得带有单取代的Cp的金属配合物的文库仍然具有挑战性。据报道，一种方便且通用的方法可用于广泛的单取代的环戊二烯基铑（I）和铱（I）配合物。该方法涉及富勒烯与广泛可用的金属前体的直接核金属化，以高收率提供一组CpRh ^I（烯烃）₂和CpIr ^I（烯烃）₂配合物。发现广泛的基于氧，氮和碳的亲核试剂可胜任该方法，并提供了环戊二烯基部分的良好调节能力。
