Visible-light photolysis of [FeCp(η6-C6H 5CH3)][PF6] 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)][PF6] 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.

Some Fe(II) ferrocenylacetylide complexes, [(Cp or Cp*)(PP)FeC=CFc], were prepared by the photolysis of the corresponding carbonyl complexes [(Cp or Cp*)(CO)2FeC=CFc] in the presence of diphosphines (PP = dppe, dppm, dmpe). The cyclic voltammograms showed two quasi-reversible waves at -0.47 to -0.84 and +0.08 to +0.12 V. The one-electron-oxidized species were isolated as relatively stable solids from the reaction of the neutral Fe(II) complexes with DDQ or FcHPF6. The oxidized complexes exhibited an intervalence transfer band at 1295-1595 nm, and the interaction parameters were calculated from the position (α2 = (0.98-2.44) ×10-2). This suggests that these are highly electron delocalized mixed-valence complexes. The IR spectra (vcc = 1956-1976 cm-1), the ESR spectra (appearance of one broad signal), and the Mo?ssbauer spectra (QS = 2.00-2.26 mm s-1) support the above suggestion. The structure of [Cp(dppe)FeC≡CFC] was determined by single-crystal X-ray diffraction.
