The preparation of the (η5-cyclopentadienyl)bis(triorganophosphane)iron halide complexes 6 - 10 involving Me3P, Me2PhP, MePh2P, (Ph2PCH2)2, and (Ph2PCH2CH2)2 is described.Reaction with organomagnesium halides RMgHal leads in the case of 9 (Ligand L-L = (Ph2PCH2)2) to complexes 13 - 19 of the type Cp(L-L)Fe-R (R = Me, Et, Bu, i-Bu, cyclopropyl, vinyl, 2-butenyl) and in the case of 10 (L-L = (Ph2PCH2CH2)2) to 21 (R = Bu).The hydridoiron complexes 12 and 20 are formed as side products in cases where the group R contains β-H-atoms and are the sole product where R = i-Pr or t-Bu.Thermolysis of the organoiron complexes 14 - 16 as well as 19 and 21 between 50 and 100 deg C also leads to 12 or 20.The Fe-β-H-elimination is reversible in the case of the (2-butenyl)iron complex 19.
