title: Visible-light generation of the naked 12-electron fragment C5H5Fe+: alkyne-to-vinylidene isomerization and synthesis of polynuclear iron vinylidene and alkynyl complexes including hexairon stars.
abstract: Visible-light photolysis of [FeCp(η(6)-C(6)H(5)CH(3))][PF(6)] using a simple 100-W bulb or a compact fluorescent light bulb in the presence of terminal alkynes and dppe yielded the vinylidene complexes [FeCp(═C═CHR)(dppe)][PF(6)] that were deprotonated by t-BuOK to yield the alkynyl complexes [FeCp(-C≡CR)(dppe)]. The reaction has been extended to the synthesis of bis-, tris, tetra-, and hexanuclear iron complexes including three alkynes of the ferrocenyl family.
