two isomers A and B. 4 and 5 react with their parent phosphanylphenols, respectively, to give diamagnetic complexes Fe(P∧O)2(PMe3) (11, 12) which dissociate trimethylphosphane to give paramagnetic compounds Fe(P∧O)2. The same phosphanylphenols react with FeCl3 to afford racemic mixtures of complexes Fe(P∧O)3 (13, 14). Structural data were also obtained from single crystals of compounds 1, 5, and 11.
