Synthesis, characterisation and catalytic use of iron porphyrin amino ester conjugates

This study described the synthesis and characterisation of C₂-symmetrical chiral Fe(iii)(porphyrin)(OMe) complexes, whose activity as cyclopropanation catalysts was investigated from both experimental and theoretical viewpoints.

Atropisomerism and conformational aspects of meso-tetraarylporphyrins and related compounds

This review provides a comprehensive description of the atropisomerism of meso-di- and tetraarylporphyrins with substituents in ortho-positions of the aryl ring, as well as in corroles and in conveniently substituted phthalocyanines. Different methods of study were examined: X-ray crystallography, NMR spectroscopy (both static and dynamic aspects), classical kinetics, HPLC and theoretical calculations. Then the four atropisomers, the tautomerism of the inner protons, the 'picket fence' concept, conformationally restricted meso-tetraarylporphyrins and the influence of the metal on the conformation were discussed based on 250 references.
