dc.description.abstract |
In the early 1990's, Drs. Fagan and Calabrese synthesized and characterized
several nickel, palladium and platinum C60 complexes. Their work played a major role in
defining the chemistry ofC60. Electrochemical techniques allowed them to propose a
suitable mechanism and establish trends for the pattern of exohedral substitution to the
C60 cage. The goal of this research is to extend Fagan and Calabrese's studies by
bonding spectroscopically and spectroelectrochemically active ligands exohedrally to the
C60 cage. This should enable the extent of communication between the phosphine ligand,
the metal and the C6o.
The synthesis of a series of maleonitriledithiolate complexes of nickel, palladium
and platinum phosphines having the formulae (dppe)M(mnt) and (PPh3) M(mnt) (where
dppe = PhzPCHzCHzPPhz, mnt = 1,2-dicyanoethene-l,2-dithiolate and M = Ni, Pd or Pt)
from the reaction ofNaz(mnt) and the appropriate (phosphine) MClz is reported. These
complexes were characterized by a combination ofmass spectrometry, IR, UV-Visible
and IH, B C and 31p NMR. X-ray diffraction analysis of all three congeners revealed
them to be isomorphous. Analysis of the diffraction data reveals that the metal centers
are all square planar. In addition, characterization of the dppe complexes by single
crystal X-ray diffraction reveals that the planar mnt ligands are tilted slightly away from
the metal square planes.
A series of (C6o)M(dppf) complexes (where dppf = 1-1'bis(diphenylphosphino)
ferrocene and M = Ni, Pd or Pt) were synthesized and characterized using IR, UVVisible
and B C and 31p NMR spectroscopy. The synthesis of these complexes are novel
because the metal is reduced in-situ. These complexes are stable in air. The 31p NMR
revealed that the phosphorus is coordinated with the respective metal center and the B C
NMR demonstrated the substitution of the C60 cage. Cyclic voltammetry was also
performed on these complexes. The dppfligand is irreversible chemically and
electrochemically. The cathodic electrochemistry correlates well with that ofFagan and
Calabrese's complexes. There are two cathodic waves which are chemically reversible,
electrochemically quasi-reversible and are shifted with respect to EO. |
