Nitric Oxide Dioxygenation by O2 Adducts of Manganese Porphyrins.

Tigran S Kurtikyan, Vardan A Hayrapetyan, Astghik A Hovhannisyan, Garik G Martirosyan, Gohar Sh Hovhannisyan, Alexei V Iretskii, Peter C Ford,

We describe here nitric oxide dioxygenation (NOD) by the dioxygen manganese porphyrin adducts Mn(Por)(η<sup>2</sup>-O<sub>2</sub>) (Por<sup>2-</sup> = the <i>meso</i>-tetra-phenyl or <i>meso</i>-tetra-<i>p</i>-tolylporphyrinato dianions, TPP<sup>2-</sup> and TTP<sup>2-</sup>). The Mn(Por)(η<sup>2</sup>-O<sub>2</sub>) was assembled by adding O<sub>2</sub> to sublimed layers of Mn<sup>II</sup>(Por). When NO was introduced and the temperature was slowly raised from 80 to 120 ... Read more >>

Nitric oxide interaction with oxy-coboglobin models containing trans-pyridine ligand: two reaction pathways.

Tigran S Kurtikyan, Shahane R Eksuzyan, John A Goodwin, Gohar Sh Hovhannisyan,

The oxy-cobolglobin models of the general formula (Py)Co(Por)(O2) (Por = meso-tetraphenyl- and meso-tetra-p-tolylporphyrinato dianions) were constructed by sequential low-temperature interaction of Py and dioxygen with microporous layers of Co-porphyrins. At cryogenic temperatures small increments of NO were introduced into the cryostat and the following reactions were monitored by the FTIR ... Read more >>
