A carbon-iron bond is also formed by the reaction of the cyclopropenium salt 185 with dicarbonyl(i/5-cyclopentadienyl)(trimethylsilyl)iron [92], (Scheme 69) In the reaction with benzocyclobutenylidene- 5-cyclopentadienyliron(II) hexafluorophosphate 186, CpFe(CO)2R (R=cyelo-C3H5, CH2-cyclo-C3H5) is converted to the allene and butadiene complexes, 187 and 188, respectively [93]. (Scheme 70)... 

Decomplexation of some metal complexes calls for drastic conditions. This is true for (/7-arene)(/7-cyclopentadienyl)iron(II) hexafluorophosphates, [FeAr(Cp)][PF6] [54, 55]. Although their chemical decomplexation is known [55 a], the most widely used method is pyrolytic sublimation at high temperatures (>200 °C) [55 b]. To evaluate MW irradiation as the method of decomplexation of such iron complexes, Roberts et al. performed the reaction in the presence of graphite [54]. They discovered that the yield of the free ligand from the [Fe( -N-phenylcarbazole)( -Cp)][PF6] complex (43) depended on the kind (flakes or powder) and amount of graphite, and on the irradia-... 

Direct formation of an organometallic complex 81 resulted when (r) -o-dichlorobenzene)(T) -cyclopentadienyl)iron(II) hexafluorophosphate was reacted with 4-methylbenzene-1,2-dithiol. The free 2-methylthianthrene could be released by heating the complex to 200-250°C (82JHC801). 4,5-... 

Representative Reaction with Piperazine Bound to Polymeric Supports (Fig. 9)31. Piperazin-l-yl methyl polystyrene resin 51a (24 g, 24.2 mmol), 776-l,2-dichlorobenzene-i75-cyclopentadienyl iron(II) hexafluorophosphate (53) (25 g, 69.6 mmol), and potassium carbonate (13.4 g, 97 mmol) are suspended in dry THF (400 ml) at RT. (Caution Exothermic reaction ) The reaction mixture is agitated overnight. Resin 54 is washed with dry THF (2 x 100 ml), CH2C12 (3 x 100 ml), MeOH (2 x 100 ml), and CH2C12 (3 x 100 ml), and then dried in vacuo at 40° to afford a red resin.
