Functionalized fullerene interactions with transition metals

The chemical derivatization of fullerenes provides for an opportunity to observe interactions with transition metals. N-functionalized fullerenes monoadducts C60-piperazine, N-methyl-3,4-fullero[60]pyrrolidine, and 5-methylsulfanyl-3,4-fullero[60]-2H-pyrrole were selected for the ease of synthesis, isolation, and the Lewis base property of the nitrogen atom(s). N-functionalized, endohedral fullerenes were supplied by Dorn et al. at Virginia Polytechnic Institute and Echegoyen et al. at Clemson University. X-ray diffraction studies were used to reveal the molecular structures and packing of the products.;A wide variety of metal fullerene interactions are reported in this dissertation. The reaction of N-functionalized fullerenes with rhodium(II) trifluoroacetate dimer produces three new transition-metal complexes and one transition-metal complex polymer. Silver(I) trifluoroacetate reacts with C60-piperazine to form an organosilver polymer complex. Silver nitrate coordination to C 60-piperazine and N-methyl-3,4-fullero[60]pyrrolidine results in a transition-metal complex and an organometallic polymer, respectively. The protonation of nitrogen addends via the decomposition of the carbon disulfide solvent results in fullerene-based ammonium salts. Last but not least, the structures the 5:6-isomer Y3 N N-ethyl-3,4-fullero[Ih-80]pyrrolidine and 5:6 and 6:6-isomers of Sc3N N-trityl-3,4-fullero[Ih-80]pyrrolidine are revealed.
