HALOALKYL COMPLEXES OF THE TRANSITION METALS I. THE SYNTHESIS AND SOME REACTIONS OF THE HALOALKYL COMPLEXES FORMED BY THE REACTION OF SODIUM (pentahapto-CYCLOPENTADIENYL)DICARBONYLIRON WITH α,ω-DIHALOALKANES

The reactions of Na (Cp=η⁵-C6H5) with α,ω-dihaloalkanes at -20 deg C yield ω-haloalkyl complexes of the type CpFe(CO)2(CH2)_nX (n=3,4 or 5, X=Br; n=3, X=Cl).CpFe(CO)2(CH2)_nBr reacts with Na togive the
