Abstract
Reduction of the cation [η5-C5H5) Fe(tripod)] PF6 with lithium aluminium hydride gives (η5-C5H5)FeH-(tripod)via an SN1 mechanism, involving prior dissociation of a phosphine ligand leading to direct attack of hydride on the metal, in contrast with the related ruthenium cations [(η5-C5H5)RuL3]PF6(L3= triphos or tripod) which give the cyclopentadiene complexes (η4-C5H6RuL3via exo-hydride attack on the cyclopentadienyl ligand [tripod =(Ph2PCH2)3CMe; triphos =(Ph2-PCH2CH2)2PPh].Keywords
