In an effort to more fully understand the chemistry of carbene complexes, two series of complexes, Cp(CO)/sub 2/Fe- (C(XR)YR)/sup +/ and Cp(CO) (L) Fe(C(SCH/sub 3/)/sub 2/)/sup +/ where X and Y are O, S, Se, and/or NR and L is CH/sub 3/NC, P(OPh)/sub 3/, P(OCH/sub 3/)/sub 3/, PPh/sub 3/, AsPh/sub 3/, SbPh/sub 3/, C/sub 5/H/sub 5/N, or CH/sub 3/CN, were prepared, and their reactivity towards nucleophilic reagents, especially amines was studied. The purpose was to correlate the reactivity patterns of these complexes with the electronic environment of the carbene carbon. Techniques for probing the electronic environment of the carbene carbon were IR, /sup 1/H-NMR, and /sup 13/C-MNR spectroscopy. The dissertation is composed of the following five sections: (I) synthesis of cyclopentadienyldicarbonyl(dithiocarbene) iron cations and their reactions with amines; (II) preparation of eta/sup 5/-cyclopentadienyldicarbonyltri (organo-thio) methyliron complexes and the structure of eta/sup 5/-cyclopentadienyldicarbonyltri (methylthio)-methyliron; (III) synthesis and spectroscopic study of eta/sup 5/-C/sub 5/H/sub 5/(CO)/sub 2/Fe(C(XR)YR)/sup +/ carbene complexes, where X and Y are O, S, Se, and/or NR; (IV) reactions eta/sup 5/-C/sub 5/H/sub 5/(CO)/sub 2/Fe(C(XR)YR)/sup +/ carbene complexes, where X and Y are O, S, Se, and/or NR, with amines; (V) synthesis, reactivity, and spectroscopic studies of eta/sup 5/-C/sub 5/H/sub 5/(CO) (L) Fe-(C(SCH/sub 3/)/sub 2/)/sup +/ carbene complexes. Each section has an introduction, experimental section, results and discussion section and references.
