Chapter 1 is a review of eta6 and eta2 coordination of an arene to a transition metal fragment. Coordination to a pi-acidic metal fragment (eta6) primarily focuses on nucleophilic substitutions on arenes activated by the metal fragments Cr(CO) 3, {Mn(CO)3}+, {RuCp}+, {Mo(CO) 3} and {FeCp}+. The sequential addition of a nucleophile then an electrophile to arenes coordinated to {Cr(CO)3} and {Mo(CO) 3} is also discussed. The chemistry of arenes bound to a pi-basic metal fragment (eta2) concentrates on the dearomatization of anisoles activated by {Os(NH3)5}2+ through a series of electrophilic followed by nucleophilic additions. Included is an introduction to the metal fragments {TpRe(CO)(L)} and {TpW(NO)(PMe 3)}.

520 $a Chapter 1 is a review of eta6 and eta2 coordination of an arene to a transition metal fragment. Coordination to a pi-acidic metal fragment (eta6) primarily focuses on nucleophilic substitutions on arenes activated by the metal fragments Cr(CO) 3, {Mn(CO)3}+, {RuCp}+, {Mo(CO) 3} and {FeCp}+. The sequential addition of a nucleophile then an electrophile to arenes coordinated to {Cr(CO)3} and {Mo(CO) 3} is also discussed. The chemistry of arenes bound to a pi-basic metal fragment (eta2) concentrates on the dearomatization of anisoles activated by {Os(NH3)5}2+ through a series of electrophilic followed by nucleophilic additions. Included is an introduction to the metal fragments {TpRe(CO)(L)} and {TpW(NO)(PMe 3)}.
520 $a Chapter 2 focuses on electrophilic additions to anisole and substituted anisoles coordinated to the {TpW(NO)(PMe3)} metal fragment. Electrophiles discussed are benzyl bromide, aldehydes, protons and Michael acceptors. The characterization of the resulting tungsten 4H-anisolium complexes is covered.
520 $a Chapter 3 describes the synthesis of tungsten cyclohexene complexes. A nucleophilic addition to a tungsten hound 2H-anisolium leads to a coordinated tungsten 1,3-cyclohexadiene. Manipulation of the diene complex by tandem electrophilic/nucleophilic additions is reported. The reactivity of tungsten 4H-anisoliums with nucleophiles is also discussed.
520 $a Chapter 4 is a report of an intramolecular aldol ring closure using tungsten 3-methyl anisolium complexes via activation of the benzylic position. A description of the synthesis, characterization of the intermediate complexes, and isolation of the organic tetrahydronaphthalene cores is presented.
520 $a Chapter 5 focuses on the synthesis of chromene cores. A nucleophile reacts at the carbonyl of a tungsten 4H-anisolium complex and the enolate oxygen closes onto C3 of the anisole ring. Elaboration of the coordinated chromenes and isolation of the organic molecules is covered. A tungsten nonenone complex was also synthesized and a description of an N-H insertion into the olefin of this compound is included.
520 $a Chapter 6 involves the synthesis and characterization of eta 2-nitrilium, eta2-ketone, and eta2-cyclopentene complexes. An analysis of the crystal structures of the eta2-nitrillum and eta2-ketone complexes is included, as well as the reactivity associated with the eta2-ketone and eta 2-cyclopentene complexes.
