资源简介：
The
chemistry of several iron(III) porphyrinates containing silanethiolate
ligands is described. The complexes are prepared by protonolysis reactions
of silanethiols with the iron(III) precursors, [Fe(OMe)(TPP)] and
[Fe(OH)(H2O)(TMP)] (TPP = dianion of meso-tetraphenylporphine; TMP = dianion of meso-tetramesitylporphine).
Each of the compounds has been fully characterized in solution and
the solid state. The stability of the silanethiolate complexes versus
other iron(III) porphyrinate complexes containing sulfur-based ligands
allows for an examination of their reactivity with several biologically
relevant small molecules including H2S, NO, and 1-methylimidazole.
Electrochemically, the silanethiolate complexes display a quasi-reversible
one-electron oxidation event at potentials higher than that observed
for an analogous arenethiolate complex. The behavior of these complexes
versus other sulfur-ligated iron(III) porphyrinates is discussed.
