摘要

(Diphenylphosphanyl)phenols C6H3(1-OH))(2-PPh2)(4-R-1)(6-R-2), abbreviated as (P<^>OH), oxidatively add to Fe(PMe3)(4) affording hydridoiron(II) compounds fac-FeH(P<^>O)(PMe3), (1: R-1=R-2 =H:2:R-1=Me, R-2=H: 3: R-1=OMe, R-2=H; 4: R-1=Me, R-2=CMe3: 5: R-1 = R-2 = CMe3) with high stereoselectivity. (2-diphenylphosphanyl)thiophenol (P<^>SH) reacts accordingly forming fac-FeH(P<^>S)(PMe3)(3) (9). Complete assignment of H-1, C-13, and P-31 signals is achieved by 2D heteronuclear shift correlations. 4,6-Ditert-butyl-(2-diphenylphosphanyl)phenol reacts with Fel(Me)(PMe3)(4) to form Fel(P<^>O)(PMe3)2 (6). 4, 5 and 9 under 1 bar of CO are converted to monocarbonyl derivatives FeH(P<^>X)(CO)-(pMe(3))(2) (7.8: X O: 10: X - S) which in solution form mixtures of two isomers A and R. 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(PO)(2), The same phosphanylphenols react with FeCl3 to afford racemic mixtures of complexes Fe(PO)l (13, 14), Structural data were also obtained from single crystals of compounds 1. 5. and 11.
