Abstract

The reactivity of [ReOCl₃(PPh₃)₂] towards o-toluidine, m-toluidine, o-fluoroaniline, m-fluoroaniline, p-bromoaniline, p-chloroaniline and p-anisidine was examined and novel rhenium(V) imido complexes [Re(NC₆H₄R)Cl₃(PPh₃)₂] (R=o-Me, m-Me, o-F, m-F, p-Cl, p-Br, p-OMe) were obtained. The resulting products were characterized by elemental analysis, electrospray ionization high-resolution mass spectrometry (ESI-HRMS), ¹H, ¹³C{¹H}, ¹⁹F and ³¹P{¹H} NMR, FT-IR spectroscopy, and X-ray crystallography. For m-toluidine, m-fluroaniline and p-chloroaniline, the rhenium(V) imido-amino mononuclear [Re(NC₆H₄R)Cl₃(H₂NC₆H₄R)(PPh₃)] (R=m-F, p-Cl) complexes and the binuclear [{Re(m-NC₆H₄Me)Cl₂(m-H₂NC₆H₄Me)(PPh₃)}₂O] complex were isolated as side products and characterized by X-ray crystallography. All six-coordinate rhenium(V) complexes display distorted octahedral coordination geometry.
