dc.description.abstract |
Bis(diisonitrile) complexes were synthesized, characterized and are reported. The
precursor to the bis(diisonitrile) complex, the bis(dinitrogen) complex, was synthesized
by reducing the appropriate metal halide, MoCls or WCI6, with magnesium metal in the
presence of two equivalents of a bidentate phosphine under an inert nitrogen atmosphere
in THF. The bis(diisonitrile) complex was then synthesized by reacting the appropriate
dintrogen metal complex with ten equivalents of 1,4-diisocyanobenzene or a derivative
thereof. The solubility of these complexes was tuned via alkyl substituents on both the
phosphine and the bis(diisonitrile) ligands although substitution on the phosphine had the
greatest effect. The trimetallic isonitrile bridged complexes were then synthesized by
combining the bis(diisonitrile) complex with two equivalents of cis(
cyclooctene)pentacarbonylchromium(O). The trimetallic complexes exhibited an
iridescent color denoting the presence of a highly conjugated x-system. The presence of
this highly conjugated system implies that these complexes may posses electrical
conductivity properties.
A new, one-pot synthesis, of sodium cyclopentadienide, NaCp, is also reported. In
this new method, dicyclopentadiene was cracked in a high-boiling, inert, non-polar
solvent while sodium metal was being melted and finely divided in the same flask. The
resulting CpH monomer then reacted with the finely divided sodium metal to produce
NaCp, with precipitates out of the non-polar solvent. The NaCp that was produced shows
remarkable stability towards air, is not pyrophoric like that produced by conventional
methods, and does in fact have Cp ring-transfer capabilities as shown by the successful
synthesis of ferrocene using the NaCp produced by this new one-pot method.
Service crystallography of samples provided by Dr. Guy Crundwell of Central
Connecticut State University is also reported. |
