A series of organyliron complexes of the type Cp(L)2Fe-R (Cp = C5H5, C5H4Me, C5Me5; L = PhnMe3-nP, N = 0-3; R = Me, Et, Bu, Ph, CH2CH2Ph, CH=CH3) have been prepared either from the corresponding iron chlorides (1-7) and organomagnesium compounds or from Cp(COD)FeLi (8, 9), organic halide, and phosphane.The thermal stability of the ethyliron complexes 17 - 24 towards β-H elimination (to give the ν2-ethylene)iron hydrides 37 - 39 or the Cp(L)2FeH compounds 40 - 48) increases with the basicity of the phosphane ligand and decreases with increasing methyl-substitution of the Cp ligand.The vinyliron compounds 29 - 32, 54, and 55 react with ethylene with insertion into the vinyl-Fe bond to give the (ν3-crotyl)iron complexes 56 - 61 as the result of isomerization.The (ν1,ν2-alkenyl)iron compounds (62), C5Me5 (63) and (67) were isolated and are stable at 20 deg C.
