NITROSOALKANE COMPLEXES OF IRON-PORPHYRINS: ANALOGY BETWEEN THE BONDING PROPERTIES OF NITROSOALKANES AND DIOXYGEN.

Article abstract of DOI:10.1021/ja00341a027

The present paper describes different preparations of iron-porphyrin-nitrosoalka complexes and their study by various spectroscopic methods including an X-ray analysis. This study definitely proves the existence of the Fe**I**I-RNO bond, establishes the end-on N-binding mode of nitrosoalkanes in these ferroporphyrin complexes and gives information on the electronic structure of the Fe-RNO bond. Moreover, it points out a striking similarity between the bonding properties of nitrosoalkanes and dioxygen as ligands of iron(II)-porphyrins. Refs.
