Synthesis, coordination chemistry, and physico-chemical properties of the 2-chloroethoxy-iron(III)(ethylthio) porphyrazine

This is the authors' abstract. We don't add key points for this paper.

Reaction of octakis(ethylthio)porphyrazine ( H 2 OESPz ) with FeBr 2 in ClCH 2 CH 2 OH at 135 °C affords the 2-chloroethoxy-iron(III)-(ethylthio)porphyrazine, ( ClCH 2 CH 2 O ) Fe III OESPz , ( LFe III OESPz ) in good yield. The spectroscopic, redox, and coordination properties of the complex and its μ-oxo dimer derivative, [ Fe III OESPz ] 2 O , are investigated and compared to those of the iron(III)porphyrin analogs.
